students complete these addition wheels by adding the number in the center to the number outside of it.
In this set of addition wheels, children will add single digits to three digit numbers. Questions are carefully selected to build students' confidence as they begin with adding a single digit to multiples of 100, then to multiples of 10 and finally to any 3 digit number. Regrouping is only required in the last two addition wheels.
