Place Value

Overview

Your student will be learning:

how to build and decompose, or break down, numbers into different parts. No matter how it is decomposed, the number still has the same value.

Example:

117 = 11 tens and 7 ones or 110 + 7 = 117

117 = 1 hundred and 17 ones or 100 + 17 = 117

117 = 117 ones

117 = 1 hundred and 1 ten and 7 ones or 100 + 10 + 7 = 117

how to find 10 less, 10 more, 1 less, and 1 more than a number using a 120 chart and/or place value blocks.
how to compare numbers to 120 using greater than and less than vocabulary as well as symbols <, >, =.

Example:

14 is greater than 3 → 14 > 3

15 is less than 18 → 15 < 18
