  • Ep 247: Avoid the Digit Trap
    Mar 11 2025

    Why do students not realize their incorrect answers are completely unreasonable? In this episode Pam and Kim discuss another trap students fall into when taught to mimic algorithms as 'the way' to solve problems.


    Talking Points:

    • The patterns in Remove a Friendly Number Over strategy
    • Important place value conversations
    • How students can be stuck dealing with only digits rather than magnitude
    • Reasonableness, or "Ish", numbers
    • Parsing out polynomials into too many pieces

  • Ep 246: Avoid the Trap of Using Less Sophisticated Reasoning
    Mar 4 2025

    If a student can perform an algorithm, have they developed the mathematical reasoning that operation calls for? Or are they answer-getting? In this episode Pam and Kim discuss a major trap students fall into when we teach mathematics as a series of steps to rotely memorize.

    Talking Points:

    • A closer look at the multiplication algorithm and a major trap.
    • Problem String that helps give students a high does of patterns for a multiplicative strategy.
    • Algorithms disregard reasonableness.
    • Memorizing an algorithm is forgetable but every strategy learned helps build mental maps to the make subsequent strategies easier to develop.
