This is a great resources for teachers and parents who are teaching children to add. It is great for children who are beginning to learn addition. This product is fun, engaging and colorful making it inviting to learners and most importantly making addition easier to understand. The individual strips help students concentrate on one number at the time, helping them understand the patterns in addition. I have used this product in a math center as well as for fast finishers. It is also appropriate for some whole class activities, partner activities and something that is assigned for homework with students who are having difficulties with addition. Just print, cut and laminate. You have a choice between printing all the numbers or just the ones you would like. You can also choose to print strips with or without answers. Color or black and white. I myself print the black and white on colored paper. Use whiteboard markers to practice.
