This is a great way to reach your visual learners who are having difficulties learning their addition facts beyond doubles.
Children can master many addition facts without using fingers if they learn this trick. All they have to do is take away 2 from a small number and give it to eight, so that their eight becomes a 10, and the small number becomes 2 less. For example, 8+5 - children can quickly take two in their minds and give it to eight, then it becomes 10 and 3, which equals 13.
Children see many demonstrations with colorful ten frames in order for them to visualize what is being explained to them.
I have to add this - today we tested this powerpoint out! Children used this lesson on the powerpoint as their base knowledge of making 10 with 8 and 9, and quickly adapted the strategy and half of the class was performing the calculations mentally once we finished learning from the powerpoint. It was wonderful to see that half of the class grasped the concept from the first time we showed them. We still had to guide them to show the small number on their fingers, and take away what 8 wanted to become a 10, or what 9 wanted to become a ten. Then, their answer was within reach, whatever left over of ones, and the ten they just made with the 9 or 8.
Some of the students are progressing with one or two mistakes out of 10 attempts in their calculations, while only 1 student didn't understand the concept. We think that he is more of a tactile learner, and we offered him linking cubes to manipulate and talk about it with a teacher or a peer in order for him to master this concept. This just shows how we all learn in different ways, and that's ok, as long as we have caring guidance of teachers in all classrooms.
I know that the price is very cheap for this successful product, but I am more interested in helping teachers, than making money. I want all the children to have access to this powerpoint, so that they have less of a trouble mastering their facts.
I love teacherspayteachers and the opportunity it offers for us, teachers, share our work so easily:)
