Materials

Preparation

Student Workbooks, and something to write with

Practice the Circles of Evaluation, using the activity sheet on Page 3 in your workbook.

In each row, there is a mathematical expression written on the left-hand column.

Go through each of these expressions, and draw the Circle of Evaluation for each one in the second column.

Once you’ve converted each of them, go to the third column and convert each one into a program that can be entered on the computer. Don’t forget to check your parentheses, and to be careful about leaving a space between each input.

Make sure students have the opportunity to practice drawing Circles from the inside-out (beginning with a large Circle and filling it in), and from the outside-in (starting with the innermost expression, and building out).
