PLUS OR MINUS 10 OR 100
Kids make a 3 digit number by rolling 3 dice or drawing 3 numeral cards...THEN they spin this spinner to see if they will add or subtract 10 or 100.
They could also choose their 3 digit number by getting out base ten blocks. If just starting out or if they need support, they could physically add or subtract their 10 or 100 blocks.
There is a recording sheet where they can write their start number, what they spin, and answer.
