There are 18 Unicorns with the “SUM” to the problem on it. There are 36 colorful presents with a number on it. Students must mentally add two numbers together to get the correct sum and then place the two presents with the Unicorn (the answer) together. This is a mental challenge activity I do with my class. At times, the two numbers they add together are correct to match a sum, however, if used then all the numbers on the presents will not be used. They have to guess the two correct numbers so that absolutely no presents and unicorns are left at the end. This makes it even more rigorous. All answers are adding two numbers together where the students must use regrouping. I place magnetic dots on the back of each unicorn and present and then I present it to my class as a whole group on the magnetic board. Later, it goes in their math stations for extra practice. An answer key and a student answer sheet is provided. My students really enjoy this game because it gives them the opportunity to think critically.
