We used pattern blocks which are in the shape of polygons- rhombus, hexagon, trapezoid, triangle, parallelogram, and square. As children manipulate the pattern blocks, they are experimenting with many mathematical concepts including fractions, patterns, symmetry, and congruence. They also develop problem solving skills and creativity.
We started our geometry unit with an introduction to polygons. Polygons are flat (2-D), closed figures with three or more straight sides that don’t cross. We sorted polygons on the Activboard.
Then we read the The Greedy Triangle by Marilyn Burns. Bored and dissatisfied with his life, a triangle visits a local shapeshifter to add another side and angle to his shape. Poof! He becomes a quadrilateral. But then he gets greedy and keeps adding angles until he’s completely transformed. As we read the story, the children used Popsicle sticks to make each polygon.
We have just completed a Powhatan village from the Eastern Woodlands region of the United States. The children worked in teams of three. Each team created a wigwam, canoe, fire pit, and tree. Then each child selected an animal and native to put in the village.
The Powhatan people lived in wigwams and traveled by foot or canoe. The men hunted, made tools and traps, and protected the village. The women made the wigwams, gathered nuts and berries, and farmed. Pocahontas was a Powhatan.
The children really enjoyed this hands-on collaborative activity!
I will occasionally share literary terms that we are learning. We spent time on alliteration and now we’ll be watching for onomatopoeia. The children love these power words and I hope you’ll be able to reinforce the concepts at home when you read together. Onomatopoeia is the use of sound words in writing. I will also encourage the children to use onomatopoeia in their own writing.
