SALT NUMBERS: The child counts (or subitises where possible) the amount of dots on the card. They then write the number in the salt. If not, shake your salt tray a little and then copy the number correctly.
My idea - Each child decorate a hand and attach it to the big tree. (Make paper hand cutouts from your children's hands. Write things they are thankful for on the hands and you will build your own thankful tree!
