Fact Families Part Two 11-18 (+, -)

These are the rest of the Addition facts that the Common Core suggests that students be able to compute mentally such as 11 + 7, 4 + 13, and 16 + 3. These obviously build on the basic single digit facts such as 1 + 7, 4 + 3, and 6 + 3. 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 Add to 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 Add to 20 program.  Otherwise the program is exactly the same as the basic Addition Rocket Math program and uses the same forms–that can be found in the forms and information drawer.

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.  One of the most common problems students have in fractions is not “reducing their answers to simplest form.”

Here's a 5 minute Educreations lessons on How the Equivalent Fractions program works.

Part of the Universal subscription package.

Equivalent fractions will help students commit 100 common equivalent fractions to memory.  Each set (A through Z) has four fractions which are displayed on a fraction number line.  Students frequently learn fractions equivalent to one,such as ten-tenths, as well as fractions that can't be reduced, for example three-fourths is equivalent to three-fourths.  Using the fraction number line will help with student understanding of why those fractions are equivalent.

Equivalent fractions, Factors, and Integers, are all pre-algebra programs that are appropriate for middle school students who already know the basic 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. You can see to the left the 25 examples of fact families taught in this program starting with Set A; 3+1, 1+3, 4-1 & 4-3.  The sheet shows the sequence of learning facts in the new Rocket Math  program Fact Families 1s-10s (+, -).  Each set that students learn from A to Y 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.

Best fit for first grade.  I separated out the 1s through 10s facts 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.  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 Fact Families 1s-10s (+, -) to the Universal subscription in April of 2017 bringing the total number of programs in the Universal subscription to 14 (the basic four operations and ten more!).  By the fall of the 2017 school year I should have the rest of the Fact Familes in addition and subtraction available.  The rest of the addition and subtraction fact families, which students could learn in 2nd grade, would be the Fact Families 11s-18s (+, -).  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, Fact Families 1s-10s (+, -),  as to how it goes for the students.

Rocket Writing for Numerals prepares students to write numerals efficiently, quickly and legibly. There are 72 pages of practice divided into four chapters which gradually increase in difficulty. (The red “Chapter 1, Chapter 2” etc don't show in the actual program!)

• Chapter 1 starts with simply having students tracing the numerals and learning to form them in the correct manner. Students work through each of the numerals and practice them in concert with other previously learned numerals.
• Chapter 2 gives more practice tracing but also requires students to learn to copy smaller examples and then write the numerals the appropriate size to fit 20 on a line.
• Chapter 3 gives more practice tracing but also has students do a one-minute timing to see if they can write 20 digits in a minute.
• Chapter 4 gives more practice tracing but also has students aim for writing 40 digits in one minute. Once they achieve this milestone they are fast enough for Rocket Math.
