R10 is working on transforming a little girl slipper pattern to an 18 inch doll slipper pattern. Her brother suggested finding the area of the shape and working from there…I believe we are working on “similar” shapes with this one.
So, we looked it up and decided the way to go was to divide the irregular shape into rectangles, squares and triangles and find the areas of those. So, she did and measured the sides. Then she got to practice:
- changing mixed numbers into improper fractions
- multiplying fractions
- changing fractions into mixed numbers
- reducing fractions
- area of a rectangle
- area of a triangle
- dividing fractions
She got more than she bargained for, but she is still plugging away!

|Our trusty Math on the Level manual for Geometry and Measurement- we reviewed the proper procedure here. I like the format of the quick reference for the teacher with MOTL.|
|Area of a triangle|
|I made this paper for her after showing her on scrap paper. I laid out the steps nicely so she could repeat it with each section. So much of what I am doing right now involves me quickly writing out an assignment for a child- not fancy but they are learning a TON!|

Sewing math is continuing to be a HUGE motivator for R10. More proof that using math instead of just doing math all the time is really effective. I’ll have to update you when the smaller pattern is finished.
