Fun Pizza counting game is a really simple and fun activity I came across on this website:
This is an ideal activity for our Hands-on learning series, wherein, we use pocket friendly , easily available materials to teach our children. For this activity, you need a paper plate, sketch pen, scissors and glue. I think the image is pretty self explanatory and you can visit the website for more details. You can also use it as a fine motor activity by asking your kiddo to stick the parts in the correct places on the paper plate.
Another additional activity you can try is teaching fractions from this. I hope you find this useful and do share your feedback after trying it!
