This product build numeracy skills by teaching subtraction using non-traditional methods, such as Singapore. Includes number line subtraction, 100 chart subtraction, decomposing subtraction, doubles and near doubles subtraction, and subtracting 100 and 10 from 3 digit numbers. Along with my addition packet, my students have developed amazing mental math strategies! Aligns to Common Core 3.NBT.2, 2.NBT.7, 2.NBT.8.
Thanks, it has been almost impossible to find practice sheets using the decomposing numbers to tens and hundreds placese strategies. Thanks so much for putting these together.
