Eight pictures of base-ten blocks (tens rods and ones cubes) for two-digit numbers. Children count the rods and cubes, write how many tens and ones, and then write the number. The Common Core standards ask 1st graders to understand that the two digits of a two-digit number stand for tens and ones.
This is the moment place value becomes visible: 4 rods and 7 cubes is 47, and 47 means 4 tens and 7 ones. If you have real base-ten blocks, build each number before writing. Next, try comparing numbers or 2nd grade place value with hundreds.
That two-digit numbers are made of tens and ones, that 10 ones make a ten, and that they can compare two-digit numbers using tens and ones.
Math blocks where a small cube is 1, a rod of ten cubes is 10, and a flat of ten rods is 100. They make place value something kids can see and touch.
