Multiplicative Reasoning LT

Research based LT resources

Use these LT resources to identify strength in student thinking and Unpack the learning trajectory using these guiding questions:
What are the big ideas? Conceptual principles and the development of the ideas underlying a concept
2) What are the multiple representations, strategies and conceptions that students need experiences with?
3) What are meaningful distinctions, definitions and multiple models?
4) What is the coherent structure? recognizing that there is a pattern in the development of mathematical ideas as a concept becomes more complex?
5) What are "bridging" standards? Knowing what underlying concepts are in between to bridge the gaps between the standards

Learning trajectory for Multiplicative Reasoning

Check out

  • Skip Counter-Uses repeated adding, additive doubling, or skip counting to solve multiplication and for measurement division (finding out how many groups) problems. Uses trial and error for partitive division (finding out how many in each group). Predicts, demonstrates, and justifies outcomes of equipartitioning collections.( )

  • Derived Facts-Uses strategies, patterns, de/composition (12 x 2 = 10 x 2 + 2 + 2) and derived combinations, such as multiplying x 9 as 10 – 1 or 7 x 8 from 7 x 7 + 7. Solves multidigit problems by operating on tens and ones separately. Quantitatively predicts the effects of changes in the number of people sharing one the size of the shares.( )
