To begin use only even number fractions. Students look at the multiples of two column, and then count down to 12 grids in the multiples of two. The students stop on the sixth grid. Ask students to record where have counted. Remind the students that they must change multiples when the selected fractions can be further reduced.
Students can visualize reduced terms and the final simple term.
When odd fractions are selected students can compare how each fraction is divided by one and itself. Students write five higher term fractions for one simplified fraction. Teacher observes and records results. All higher terms and reduced fractions are hung on the tree. Odd fractions are hung on a crab apple tree.
