ready to find out how to make the cheapest math manipulatives ever?
Use the ruler and marker to draw a number line on the Ziploc Slider bag.. Then use the marker to color the slider piece. Cut out a piece of colored paper that will fit snuggly into the bag. This adds color to the bag, so that the numbers can be seen more easily. You now have a counter! Students can use these to help with addition, subtraction, and more. They can use the number line and slider to help figure out the answers. Example… 9-4. Student can slider the slider to 9 and then slide it back 4 spaces. This will land them on 5 letting them check their work, or help with their work.
