This is a slideshow to review multiplication, factors and multiples for 4th grade. I use this for a review before the NYSED Math State Test. This contains a review about 3,4 x 1 digit multiplication and 2x2 digit multiplication, as well as a brief review of factors, multiples, and prime/composite numbers. The multiplication strategies included are: area model, partial products, and the standard algorithm. The problems on the last slide align with the purple Ready Book aligned to the Next Gen.
