In our last math unit of the year, we have been working hard to distinguish 2-D and 3-D shapes, and to describe them using defining attributes. We have been playing math games involving trapezoids, rhombuses, hexagons, and triangles.
We searched our classroom, and also went on a "shape walk" around the school one day, looking for examples of 3-D/solid shapes. It was interesting that cones and pyramids didn't come up often, but we saw many rectangular prisms and spheres!
But we haven't been only studying shapes in math time. We've been keeping our brains strong with operations as well, particularly focusing on adding or subtracting ten from any number. This coincides with a deeper understanding of place value. We play games like "pop" to practice the counting sequences starting at a number like 2 and then adding 10, adding 10, adding 10: 2, 12, 22, 32, and so on. Our whole calendar pattern for the month of May has had us "hopping" around the number grid, adding or subtracting tens or ones or both. The students have also had fun completing a few "hidden picture" grids, where they need to solve a +10 or -10 problem, then color the solution in a certain color to discover a picture.
