In Episode 67 revisited the Development of Mathematical Reasoning (DMR) and we described how students can solve addition problems with Counting Strategies. What about the addition algorithm and multiplication and division problems? In this episode Pam and Kim explore the Development of Mathematical Reasoning even further, and discuss how important it is that we help students become more sophisticated. It's more than just answer getting. And stay tuned to the end for a freebie!

• Examples of solving addition problems with bigger numbers using Additive Reasoning.
• Examples of solving multiplication problems with Counting Strategies, Additive Reasoning and Multiplicative Reasoning.
• Examples of solving division problems with Counting Strategies, Additive Reasoning and Multiplicative Reasoning.
• Brand new free infographics of the Development of Mathematical Reasoning.
• Videos of students solving problems using the different types of reasoning to help you use the DMR in your classroom to identify where your students are in their reasoning.
