A challenging way to practice numbers!

I was watching one of my sons’s favorite cartoons one of these days and suddenly I realized that they were showing a great way to work with numbers in class. In the cartoon they were studying Science so they were estimating how many of certain objects there were in a recipient. Immediately I thought about getting some recipients myself and put into them something countable so that my students could try to guess how many of those objects we had. This could be a challenging exercise and they would be practicing numbers at the same time by making sentences like: “I think there are 56 beans” or “I guess there are 30 buttons”. Here are some ideas of material we can work with: coins (they give a brief look), small pictures, colored buttons, beans, etc. Have a bright Monday!
