Teaching guide

What students learn

Partition, regroup and rename two- and three-digit numbers in different ways, including understanding the job a zero does.

234 = 2 hundreds + 3 tens + 4 ones
How to teach it

Build numbers with base-ten blocks or bundles of ten, then say the value of each digit ('the 3 is worth 30'). Expand numbers (300 + 40 + 2).

Worked example
Count the tens rods and the ones blocks. What number do they show?
Answer: 81
Why: 8 tens = 80, 80 + 1 = 81

Generated and checked in code, so it is correct.

Watch out for

Reading a digit at face value regardless of its column, and dropping the zero as a place-holder (e.g. writing 32 for 302).
