My question is whether 13 x 6 = (10×6) + (3×6) goes beyond what this standard intended for third grade? Basically, I’m wondering if it’s ok to move into double digit factors or if 3rd graders should just be working with single digit factors. Thanks, in advance, for any clarification.
3.OA.7 calls for third graders to fluently multiply and divide within 100. So double digit factors are all good as long as the product is between 0 and 100.
