a-MAZE-ing Secret Paths
 


Activity Overview

Students learn to add and subtract numbers using the calculator. They investigate patterns in place value and explore relationships between numbers on the hundred chart.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 17 - 20 from the attached PDF file for your class

    		•

    		During the Activity

    		Distribute the page to the class.

    Follow the activity procedures:
  • Select a number from the hundred chart and note the number to the right of it
  • Observe that the number to the right is one more than the original number
  • Investigate numbers to the left, above, and below the original number and investigate the relationship
  • Select two numbers on the hundred chart and draw a path between the numbers, moving horizontally and vertically from square to square
  • Use the calculator, start with one number, and use number operations to trace the action steps to reach the second number
  • Repeat the activity using different paths
  • Observe which steps lead to the left, to the right, and what happens when the path moves up and down
  • Understand the pattern in the place values and the effect of adding and subtracting using the calculator

    		After the Activity

    		Students complete the Recording Sheet.

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
