What is AlgebraicReasoning?What is AlgebraicReasoning?• Algebraic reasoning is a process in which students generalize mathematical ideas from a set of particular instances, establish those generalizations through discourse, and express them in increasingly formal and age-appropriate ways (Kaput, 1995;1999)

What does REALISTIC mean to children and their teachers?• Tasks are engaging to students because they are grounded in real world contexts
• Accessible to all students• Encourages students to construct models of/for reasoning

How can submarine sandwiches make math real? (an example from CFLM)
How can submarine sandwiches make math real? (an example from CFLM)• Sharing 3 subs among 4 kids, 4 among 5 kids, 3 among 5, and 7 among 8 kids– Was it fair?– How can the subs be shared?– How much will each child in each group get if the subs are shared equally?
– How can these quantities be compared?
