Learning to Subtract Integers (positive and negative numbers) Learning Track

List of Learning Tracks Continue to purchase

How does this Learning Track teach?

Learning to Subtract Integers displays problems on a vertical number line and then teaches students two rules about how to solve problems in which you subtract positive and negative numbers.

Rule 1:  When you subtract a positive number, go DOWN.
Rule 2:  When you subtract a negative number, go UP.

Doing problems on the vertical number line is more intuitively appealing because UP is more and DOWN is always less.  This makes crossing zero a little easier to comprehend.

Total of four problem types to learn.

Students learn how these two rules play out with two types of problems: when starting with a positive number and when starting with a negative number. Students gradually learn all four types of problems.  On each worksheet they see how to solve each problem type using the number line working with their partner.  Then students learn to recognize the pattern of each problem type by orally answering several examples of each type with their partner (going around the outside of the page).  You will probably not be surprised that there is a one-minute test on each set.   Students are to be 100% accurate and to meet or beat their goal from the special writing speed test for Learning to Subtract integers (the fastest goal is only 28 problems in a minute).

Online Video lessons can teach students the process.

Here are links to the 4 online lessons teach students how each type of problem is solved and why it is correct. These are available in the virtual filing cabinet as well.

Skip Counting Learning Track

List of Learning Tracks Continue to purchase

What is Skip Counting?

Not counting while skipping!  Learning to skip count by fours is to learn this sequence by memory: “Four, 8, 12, 16, 20, 24, 28, 32, 36, 40.” Skip counting is also known as learning the “count-by” series.

Why teach skip counting?

Skip counting is the best way for students to prepare for multiplication. It teaches the concept of successive addition which is the root of multiplication.  In addition, skip counting helps prepare the ground for memorizing the multiplication facts.  Students who have learned to skip count find the chore of memorizing multiplication facts much easier. This Learning Track is excellent for second or third grade students after learning addition and subtraction facts and before learning Multiplication facts. Skip counting is not something older students past fourth grade really need to do, and of course, it’s no longer useful once multiplication facts have been committed to memory.

Each series is broken into easy-to-learn parts

Students learn part of each sequence on a page, then the next page they learn the rest. For example: in Set O students learn to count by 3s to 12, (3, 6, 9, 12) then in Set P they learn to count by 3s to 21 (3, 6, 9, 12, 15, 18, 21), and then in Set Q they learn to count by 3s to 30 (3, 6, 9, 12, 15, 18, 21, 24, 27, 30).

How does Skip Counting teach?

As in most Worksheet program Learning Tracks, students practice with a partner who has the answers. Because of the way the rockets go around the page (see above), students and their checkers will have to pick up the pages and turn them as they are working. You’ll be able to see if they are really engaged and they will have fun turning the page around. The test in the center has them write the count-by series they have learned for one-minute and they need to meet or beat their best–just like the rest of Rocket Math. Here is the sequence students will learn in this order: 2s, 5s, 10s, 9s, 4s, 25s (so they can count quarters), 3s, 8s, 7s, and 6s. Probably our most fun Learning Track.

Learning to Add Integers (positive and negative numbers) Learning Track

What does this Learning Track teach?

Learning to Add Integers teaches four types of problems to solve.  It displays problems on a vertical number line and then teaches students two rules about how to solve problems that add positive and negative numbers.
Rule 1:  When you add a positive number, go UP.
Rule 2:  When you add a negative number, go DOWN.

Doing problems on the vertical number line is more intuitively appealing because UP is more and DOWN is always less.  This makes crossing zero a little easier to comprehend.

Add-Subtract Fact Families from 11 to 18 Learning Track

List of Learning Tracks Continue to purchase

Add and Subtract Fact Families are a different way to learn facts.

A number of math programs around the country introduce math facts in families.  Now Rocket Math does too!  A fact family includes both addition and subtraction facts. This program is Part 2 of Fact Families, coming after Fact Families 1 to 10. You can see above the 18 examples of fact families taught in this program starting with Set A; 11-2, 11-9, 9+2, & 2+9.  The sheet above shows the sequence of learning facts in the new Rocket Math  program Add-Subtract Fact Families from 11 to 18.  Each set that students learn from A to R adds just one fact family to be learned, so it isn’t too hard to remember.  (That’s the Rocket Math secret ingredient!) 

A chart that shows the set of math fact family 5, 3, and 2 in Addition and Subtraction.Learning math facts in families, is gaining in popularity these days.  Logic suggests that this would be an easier way to learn.  However, the research is not definitive that this is easier or a faster way to learn facts than separating the operations and learning all addition facts first and then learning all subtraction facts.  But learning in fact families is a viable option, and I wanted to have it available for Rocket Math customers.

Fact Families from 11 to 18 is part two and fit for second grade.

These facts come after the Add and Subtract Fact Families 10, which should be learned in first grade, so these are best for second grade.  The 25 fact families in 1s through 10s facts are just enough for one Rocket Math program.  It is a good and sufficient accomplishment for first grade.  With the 11 to 18 part for second grade there will be a lot of review.  In fact sets S through Z are all review. I have heard that some first grades prefer to keep the numbers small but to learn both addition and subtraction–so this program accomplishes that.

We  most sincerely want students to be successful and to enjoy (as much as possible) the necessary chore of learning math facts to automaticity. Please give us feedback when you use this program, Add-Subtract Fact Families 11 to 18,  letting us know how it goes for the students.

Flash news!! Someone looking for a master’s or doctoral thesis could do a comparative study of students using the fact families vs. the separated facts in Rocket Math. This could easily be a gold standard research study because you could randomly assign students to conditions within classrooms–the routine is the same for both–just the materials in their hands is different!  Just sayin’…

Best fit for first grade.  Dr. Don separated out the facts to 10 from the 11s-18s, because these 25 families are just enough for one Rocket Math program.  It is a good and sufficient accomplishment for first grade.  Some first grades prefer to keep the numbers small but to learn both addition and subtraction–so this program accomplishes that.

Add-Subtract Fact Families to 10 is the first half.  The rest of the addition and subtraction fact families, which students could learn in 2nd grade, are the Add-Subtract Fact Families 11 to 18.  We most sincerely want students to be successful and to enjoy (as much as possible) the necessary chore of learning math facts to automaticity.

Dictating Sentences (Rocket Spelling) Learning Track

List of Learning Tracks Continue to purchase

Developing Fluency with spelling.

Dictating Sentences is spelling with a twist.  Instead of spelling one word at a time, in Dictating Sentences students are asked to write an entire sentence from memory.  They work in pairs and their tutor has the student repeat the sentence until it is learned.  Then the student has to write the whole sentence from memory.  It turns out this is considerably harder than writing words on a spelling test, so it is challenging practice, and does a lot to help students develop automaticity with spelling.

If you have to stop and think of the spelling of a word while you are trying to write, it distracts you from thinking about what you are trying to write.  Students are more successful and better able to show what they know and better able to focus on learning when their tool skills have developed to the level of automaticity.

10 minutes a day practice develops fluency and automaticity.

Developing automaticity with math facts and with spelling requires a lot of practice.  Daily practice is best and a few minutes a day is optimal.  That is why Rocket Math is designed the way it is–to provide that daily practice.  Dictating Sentences gives each member of the pair ten minutes a day of practice writing sentences composed of words they know how to spell and must spell correctly.

Working in pairs.  As you know from Rocket Math practice, students enjoy working in pairs.  And when one partner has an answer key the practice can be checked and corrected.  Sound research shows that immediate correction and editing of misspelled words is the fastest way to learn the correct spelling, so that’s what we have the student tutor do.  After each sentence is written every word is checked and practiced again until it is correct.

Mastery learning. The program is structure so that all the words are learned to the level of automaticity.  Students keep working on a sentence until it can be written without any errors.  They work on the same lesson for as many days as is needed for them to spelling every word perfectly in all three sentences.  Each sentence persists for two or three lessons, so that the student is required to write it from memory and spell every word perfectly for several days in a row.

500 Most common words.  Dictating sentences systematically practices the 500 most common words that students need in their writing.  It includes all of Rebecca Sitton’s 400 Core Words.  It also includes the 340 words that children most need for writing according to writing researchers Harris and Graham.   When students know these words to the level of automaticity, they will be able to write fluently and easily.

Earning points for being correct and going fast.  Students earn two points for every word that is spelling correctly the first time.  Every word on which there is an error is worked on until it too can be spelled correctly, earning one point.  The faster students go during their ten minutes, the more points they can earn.  Students graph the number of points earned and try to beat their own score from previous days.  Teams can be set up and competition for the glory of being on the winning team can enhance the motivation.

Individual Placement.  There is a placement test.  Students begin at the level where they first make a mistake.  Student partners do not need to be at the same level, so every student can be individually placed at the level of success.

Equivalent Fractions Learning Track

List of Learning Tracks Continue to purchase

Why commit to memory equivalent fractions?

We expect students to reduce their answers to the lowest terms, but how can they if they don’t recognize them?  To do this easily, students need to know that six-eighths is equivalent to three-fourths and that four-twelfths is equivalent to one-third.  While they can calculate these, it is very helpful to know the most common equivalent fractions by memory.  Not knowing these by memory accounts for the most common problem students have in fractions: failing to “reduce their answers to simplest form.”

Each set (A through Z) has four fractions which are displayed on a fraction number line.  In addition to pairs of equivalent fractions, students frequently learn fractions equivalent to one, such as ten-tenths.  They also memorize fractions that can’t be reduced, for example three-fourths is only equivalent to three-fourths. Students use a number line and identify equivalent fractions by circling an equivalent pair of fractions.  They understand why they are equivalent as well as memorizing the pair.

Equivalent fractions, Factors, and Integers, are all pre-algebra programs that are recommended for upper elementary and middle school students who already know the basic facts.

How to do (compute) multi-step division problems

After becoming fluent with division facts, the best way for students to retain the knowledge of those facts is by doing division computation.  If students have not been taught division computation, this program breaks it down into small, easy-to-learn steps that are numbered in a teaching sequence that leaves nothing to chance.

Assessment to find which skill to teach first

There is an assessment available so you can test and see where to begin instruction. Find where the student first starts having troubles and begin teaching there.

Skills in this Learning Track

Note that the number for each skill gives the grade level as well as indicating the teaching sequence.  Skill 3b is a 3rd grade skill and after skill 3c is learned the next in the sequence is skill 4a.  The sequence of skills is drawn from M. Stein, D. Kinder, J. Silbert, and D. W. Carnine, (2006) Designing Effective Mathematics Instruction: A Direct Instruction Approach (4th Edition) Pearson Education: Columbus, OH.

How to teach this Learning Track

For each skill there is a suggested Teaching Script giving the teacher/tutor/parent consistent (across all the skills we use the same explanation) language of instruction on how to do the skill.  The script helps walk the student through the computation process.  For the teacher, in addition to the script, there are answer keys for the five worksheets provided for each skill.

Each worksheet is composed of two parts.  The top has examples of the skill being learned that can be worked by following the script.  After working through those examples with the teacher the student is then asked to work some review problems that are already known.  The student is asked to do as many as possible in 3 minutes—a kind of sprint.  If all is well the student should be able to do all the problems or nearly all of them, but finishing is not required.  Three minutes of review is sufficient for one day.

There are five worksheets for each skill.  Gradually as the student learns the skill the teacher/tutor/parent can provide progressively less help and the student should be able to do the problems without any guidance by the end of the five worksheets.  There are suggestions for how to give less help in the teaching scripts.
