This is a hands-on game that will help students understand more clearly the concept of regrouping when adding or subtracting. Although it is designed to be used as a game for independent practice, it can also be a great manipulative resource for the teacher to have students use it when they are actually learning to regroup. It includes two math mats with room to place ones and tens, apples to be used for the ones, bowls of apples to be used for the tens, cards with additions and subtractions, full explanation on how to use the game and an answer key for self-correction. If you only want to reinforce either addition or subtraction, just remove the cards you won't use and keep them apart. This is the Spanish version of " Addition and subtraction with regrouping. Math mats".
