This activity could be used prior to or following a physical manipulative activity using Cheez-It type crackers.
Students will estimate and then click and drag the “Cheez-It” squares from the grey work space to cover the grey box.
Students should make an educated guess (estimate) on how many Cheez-It crackers might be needed to cover the square.
Students can also calculate the area and the perimeter (an actual Cheez-It is 26mm x 24 mm) as part of the activity.This activity could be adapted down for estimation for grades 1 and 2 or up for calculation and conversion of metric units in grades 4 and 5. Look at the activity and determine its best use for your students.
