Take a 100's chart and copy it on two different colors of paper. Cut strips horizontally and tape every other color together into a long train. So 1-10 would be white, 11-20 would be green, 21-30 would be white, 31-40 would be green, etc. Then cut two slits in an index card and fish the train through.
Uses: use in 1st grade to help kids with number sense. Show them a number in the window and see if they can name the number that comes next, or before. You can also use it to help kids cross decades (after 39 is....)
Take some poster board and fold in half so you have a piece about 15" x 4". | |
Cut three doors in on the front flap, like a flip book. Underneath make some sentence strips with three numbers on them. Slide them underneath and flip the doors open for the kids to guess the numbers. Uses are similar to those with the strips.
Good luck.
