Finding Patterns PPT, Part 2: Teaching New Courses

Xiaohong put on a bracelet according to the rules, but two beads fell off. Which two beads fell off?

What do you know from the picture?

①This bracelet has two kinds of beads, yellow and blue.

②This bracelet is made of 2 yellow beads, 1 blue bead, 2 yellow beads, 1 blue bead... worn repeatedly.

③This bracelet has 2 beads missing.

Think about it, how do you know which beads are missing from this bracelet? Discuss this in a group.

①The first dropped bead is a yellow bead, because now there is only one yellow bead behind the last blue bead on the right side of the bracelet, and there should be 2 yellow beads. So the first one dropped is the yellow bead.

②The second one dropped is a blue bead. Because behind the two yellow beads are blue beads.

Makes sense! What Xiaohong dropped from the bracelet was 1 yellow bead and 1 blue bead.
