Is it CPM? Was it a middle school?

@mnmmath.bsky.social I'm really looking forward to it!

That one will be fun to show!

Reading this was like a published sigh of relief.

We played Make 10 and Fraction Tracks from TERC Investigations. We explored was of adapting each to meet the needs of all mathematicians. My session had teachers from elementary through high school!

In the algorithm, you lose track of the place value, you just follow a procedure. In the 2nd strategy, 110 is decomposed into 100 and 10 and the parts are multiplied by 4,259, then added together. There are similarities, but one strategy holds on to place value. Both yield a correct answer.

deserve the right to joyful, challenging math and also deserve the right to come at mathematical ideas through their own strategies #ElemMathChat
