Teaching guide
Represent whole numbers in expanded form using place value and powers of ten.
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).
Generated and checked in code, so it is correct.
Reading a digit at face value regardless of its column, and dropping the zero as a place-holder (e.g. writing 32 for 302).
