New in the Math Mammoth online practice section!

Fact families (addition & subtraction)

Fact families is one of the main approaches I've used for addition & subtraction facts in the Math Mammoth curriculum. For example, in the online practice program, you could choose to practice fact families with 6. This means you will get addition & subtraction problems like what you see in the picture below -- and also including missing number problems.

A customer asked me about reviewing addition/subtraction facts from 1st grade. The child is currently in 2nd grade but those facts continue to be a weak point, despite flash cards, daily drills on paper, and online drills in the past.

Here's my answer...

Check out these videos, which show you how the addition facts are taught in MM grade 1.

Subtraction facts don't need memorized separately. If you know that 5 + 4 = 9, from that you also know that 9 - 4 = 5 and 9 - 5 = 4. So, subtraction facts become "missing number" addition problems.

For example, 7 - 3 = ?

Think: which addition fact is this one: 3 + ___ = 7?

You can most likely make worksheets for her based on those videos, but if you want an actual book, check out these:

Here are neat puzzles to review factors in multiplication, the multiplication tables -- and consequently, the basic division facts -- all in the same "package"!

Or, just use them as cool logic puzzles. ☺

They're called Find the Factors puzzles.

This page explains how to solve them.

On this page you'll find a vast amount of them, as Excel spreadsheets:

Like the author says, "The more multiplication facts you know, the easier these puzzles become. Working on these puzzles can help you learn the multiplication table better."
