Slide Deck: Using Math Manipulatives as Tools of Proof
Summary: Math manipulatives are often used as 'answer getting' tools. For example, when students are asked to show equivalent amounts to 3/4 using fraction bars, many students just match and see what fits. Are they thinking and developing a deep conceptual understanding of equivalence or are they just matching? This, handson session focuses on how to use readily available math manipulatives and materials in a way that fosters reasoning, justification, and flexible thinking. You will leave this session with a deeper understanding of how students at the upper elementary and middle school levels can model their thinking and understanding using math manipulatives.
Number Bead String Resources (from Amazon):
The list below will make 20 number bead strings.
I recommend each student making two number bead strings.
One for school use and 1 for home use.
Buy extra just in case beads get lost.
