Can you solve this Math problem?

Hello Year 3! Hope you are very well. You will have your new Home Learning Pack next Monday.

Here you have a really fun Math problem to solve it. It will be helpful if you could use 20 coins to find out the solution, but if not, just use paper and a pen to do your calculations.

Please let me know what your answer is. I am relly looking forward to hearing from you. Have a great day!

Miss Olavarria
