We made a sea star quilt this week this week. First we read an informational poem to learn a few things about fascinating sea stars, in particular that they have five arms. For the patchwork blocks, we had to first calculate exactly how many squares of each color we'd each need to fill the pattern. This was extra challenging because several brown squares had to be cut into halves of fourths to make the triangles (we're working with wholes, halves, and fourths in our current Number Corner pattern too). It was a great chance to practice careful cutting and use of glue, as well!
When the blocks were all assembled to make a quilt we noticed many patterns within it and made lots of interesting math observations. The quilt provided many opportunities to practice counting by 5s-- can you find all the ways to see groups of 5 in this quilt?
After it was posted on the wall we reviewed all the mathematical observations and took tuns proving them by pointing out how each observation was derived.
