We continued to study shapes during our math time this week. We started the week combining triangles, rectangles and squares to form new shapes. We learned about: rhombuses, trapezoids, parallelograms, and hexagons. We also found that we could combine and transpose our shapes to create patterns.
Later in the week we began exploring with 3-dimensional shapes! We touched on the following shapes…
We learned about the attributes of each of these shapes. We also briefly discussed how these 3-D shapes compare to the 2-D shapes. For example: the 3-D sphere is just like a 2-D circle and the 3-D rectangular prism is just like a 2-D rectangle. We combined different shapes together to create new shapes and also tried to break large shapes apart into smaller ones.
Then, we moved into measurement. We discussed how in the old days before rulers were invented, people used to use their body parts to measure objects. This kids couldn’t believe this was true and brought up a very big problem… our feet and fingers are different sizes! We realized that when we use a common unit – like a paperclip – we all get the same results. To test this theory, we used paperclips to measure various things in our math book and around the room.
We also introduced the word “length” and talked about how to line up measurement tools properly to get the most accurate measurement. We compared lengths of objects from shortest to longest and longest to shortest (1, 2, 3).
