There are 13 jigsaws in this product. Each jigsaw targets particular skills, but they all involve sequencing.
It also contains a complete grid which you can cut up and target skills that your learners need. It has two different fonts as I have found some of my learners need me to use the straight back version of the number nine.
The sequences I use in these jigsaws are zero to ninety-nine and one to a hundred. The 0-99 jigsaws display each tens family on a horizontal line. One of the jigsaws is cut vertically for this purpose.
I find after a few jigsaws my intervention kids have a better idea of the patterns in the board and are more skilled at number patterns in general. When my group are putting a jigsaw together they are hearing me use concepts such as number before, number after, number between, ten more than, ten less than.
I have these jigsaws pre-cut in plastic sleeves with a blank hundreds board to glue or tape on to. The muti-sensory nature of this activity makes it especially valuable for particular students. I have jigsaws with blanks so some have to fill in the blanks before they start. This is an extra element of sequencing that consolidates the skills. I even send them home for homework when parents want to help (and I let them do the cutting up).
