    While I rarely seem to hav time for the activities themselves, I love to talk about applications. Recreating a plan with nonstandard resources is life skill. Pallet projects, community gardens from recyclables and other repurposing are great for kids (& budgets!).

    Kids examine one pattern block design then re-build it using totally different blocks. How could you use this lesson to engage all students in the mathematics? Reply using .

    Loved doing this every year with my 3rd and 4th graders to introduce and reinforce conceptual understanding of fractions. Then we played games and kept using it as a tool in their math tool belt.
