The Learning to Subtract Integers Learning Track is one of 26 included in a Universal Level Worksheet program subscription. Available in a trial subscription for 60 days.

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).

4 online lessons teach students how each type of problem is solved and why it is correct.

(1) Subtract Integers Set A Positive subtract a positive

(2) Subtract Integers Set B Positive subtract a negative

(3) Subtract Integers Set G Negative subtract a negative

(4) Subtract Integers Set L Negative subtract a positive

Uncategorized extras Add-Subtract Fact Families 11 to 18 $15.00

The “Add-Subtract-Fact-Families-11-to-18” Learning Track is one of 26 included in a Universal Level Worksheet program subscription, which is available to try for 60 days.

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 to the left the 18 examples of fact families taught in this program starting with Set A; 11-2, 11-9, 9+2, & 2+9. The sheet shows the sequence of learning facts in the new Rocket Math program Fact Families Part Two 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!)

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.

Part Two is a Best fit for second grade. These facts come after the facts in 1 to 10, typically 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.

I added Add-Subtract Fact Families 11 to 18 to the Universal subscription in August of 2018. As always, new programs are added to the Universal subscription without additional cost as soon as they are available.

I 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 me feedback when you use this new program, Add-Subtract Fact Families 11 to 18, as to how it goes for the students.

Uncategorized extras Division–Learning Computation $15.00

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.

Note that the number for each skill gives the grade level as well as indicating the teaching sequence. Skill 3b is a 3^rd 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 (4^th Edition) Pearson Education: Columbus, OH.

(3b) Dividing 1-digit divisor and quotient with remainder.

(3c) Division equation with ÷ sign; facts with no remainder

(4a) 1-digit divisor; 2- or 3-digit dividend, 2-digit quotient; no remainder.

(4b) 1-digit divisor; 2- or 3-digit dividend, 2-digit quotient; remainder.

(4c) 1-digit divisor; 2- or 3-digit dividend, 2-digit quotient with zero; remainder.

not yet completed levels–coming soon

(4d) 1-digit divisor; 3- or 4-digit dividend, 3-digit quotient.

(4e) 1-digit divisor; 3- or 4-digit dividend, 3-digit quotient with zero.

(4f) 1-digit divisor; 4- or 5-digit dividend, 4-digit quotient.

(4g) Rounding to the nearest ten.

(4h) 2-digit divisor; 1- or 2-digit quotient, all estimation yields correct quotient.

(4i) 2-digit divisor with incorrect estimated quotients.

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.

Uncategorized extras Subtract from 20 (e.g., 18-15, 15-5, 19-8)

Rated 5.00 out of 5

$15.00

The Subtract from 20 Learning Track is one of 26 included in the Universal Level Worksheet program subscription, which is available to try for 60 days.

These are the rest of the Subtraction facts that the Common Core suggests that students be able to compute mentally such as 18-15, 15-5, and 19-8. These obviously build on the basic single digit facts such as 8-5, 5-5, and 9-8. Students should find these fairly easy to master but they still need some practice to commit them to memory. LOOK OUT! Because all the answers are two digits, the number of problems students can be expected to answer will go down! You must give the special Subtract from 20 Writing Speed Test to set new, lower, goals for your students. To the left you can see the sequence of facts that will be learned in the Subtract from 20 program. Otherwise the program is exactly the same as the basic Subtraction Rocket Math program and uses the same forms–that can be found in the forms and information drawer.
