Bundle it up by tens!
First grade is when kids discover that ten ones can be bundled into one ten. They learn that two-digit numbers are made of tens and ones: 46 = 4 tens and 6 ones. They find 10 more and 10 less than a number in their heads (36, 46, 56), compare two-digit numbers with >, < and =, and count all the way to 120. They also add tens and ones, like 40 + 7 or 32 + 20. The click moment comes when a child adds 10 to 58 without counting and just says "68, the tens went up!"
Base 10 is easiest to understand when kids can hold it. These moves go from blocks to pictures to numbers.
Give kids a pile of straws or cubes and ask them to count it. Most will count by ones. Then show them how to bundle groups of ten with a rubber band and count again by tens. Seeing 47 straws become 4 bundles and 7 loose is unforgettable.
Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.

Why it works: pairing a picture with each word gives kids two ways to remember it, a well-tested principle of how people learn (Mayer, 2009).

Why it works: handing over the work step by step, from teacher to student, is one of the most widely used teaching frameworks (Pearson and Gallagher, 1983).

Base 10 means our number system groups by tens. First graders learn that two-digit numbers are made of tens and ones, so 52 is 5 tens and 2 ones.
Use a hundred chart: 10 more is one row down and 10 less is one row up. Kids quickly notice that only the tens digit changes. Base 10 blocks show the same idea with a rod added or taken away.
They're math tools where a small cube is one, a rod is ten, and a flat is one hundred. First graders mostly use cubes and rods to build two-digit numbers.
Bundle crayons, pasta or craft sticks into groups of ten. Ask your child to build a number like 34, or count a pile by making tens first. Dimes and pennies work great too.
