Phillips Math

This activity reviews decimal subtraction using the standard algorithm. Students will use algebraic thinking to fill in missing digits in the minuend, the subtrahend or the difference. The digits provided fit the blank spaces exactly, which allows students to self-check or correct their work. Digits for the front and back are printed separately to allow for activity chunking. A pencil may be used instead of gluing digits.

This activity models decimal multiplication using a hundredths grid. Students will solve for the missing factor or product, or, will write and solve an equation based on the pictured model. There are 24 cards, 2 blank models, an answer sheet and answer key provided.
