Are you a 2nd Grade teacher who loses sleep over teaching the standard algorithm for multidigit addition and subtraction? Or a 3rd or 4th grade teacher trying to remediate students who can’t successfully add and subtract multidigit numbers? What if I told you it...

If you teach 3rd grade, you know that some students come to your class not knowing their basic addition and subtraction facts. And in 4th and 5th grade, there are students every year that lack mastery of ANY of their basic math facts—addition, subtraction,...

Computational fluency is still a goal for mathematics instruction. What’s changed is how we approach computation. We have shifted from teaching one method—typically the standard algorithm—to a strategy-based approach. Today, I’ve got an easy little game...

A while back, I wrote a post about incorporating mathematical reasoning into computation practice. In that post, I shared a free long-division choice board. Today, I am sharing a free 3-digit subtraction choice board to illustrate how easy it is to adapt tasks so you...

Do you wonder where fact families are found in the current standards? The fact is, current standards don’t actually mention fact families at all anymore. Instead, they refer to “the relationship between operations.” An understanding of this...
