Teacher Guide: Lesson 2.3

The Weekly Reader Connections feature on Kids' Place Houghton Mifflin Math provides children with additional information about the topics that appear in the Curriculum Connection feature in their student books.

The article “This Tree House is Tops!“ describes a tree house built 10 feet off the ground, but with a ramp which makes it wheelchair accessible. The builder of the tree house, Bill Allen, a former member of Vermont's Make-A-Wish Foundation, had gotten architects, builders, and many volunteers to help build the tree house on the campus of a summer camp that holds a week-long camping experience for children with cancer on Lake Champlain.

The Word Wise activity introduces children to the meaning of "compound word." Children choose from a list of root words to build their own compound words. Children then write definitions for their words. The words that children create do not need to be real words, but they should be able to create a reasonable definition of their words that combines the meanings of the two root words.

The Data Hunt activity has children design a tree house. Children need to draw a tree house in a tree, complete with a door, windows, and some means of entry (stairs, ramp, rope, etc.).

Students are then asked to draw height dimensions for the tree house, the door, the window, the tree, and the distance from the ground to the top of the tree house. Check students' diagrams to see if they add up. Remind students that if the height of the tree house is 7 feet, and the distance from the ground to the floor is 8 feet, then the total height from the ground to the top of the tree house should be 15 feet. Have students discuss their chosen dimensions. Ask them to discuss their tree house designs.
