Teaching Number Facts up to 20

Tens Frame

Tens Frames for 15

Triangle

In my first grade class (Second Year Infants) I always use ten frames and triangles to teach number facts up to 20. They are great visuals that can get students to recall number facts quickly. I also teach both addition and subtraction together so that students can actually play around with the signs and the facts so that they can see patterns and form relationships.


Number facts can be very difficult for students to grasp if it is not done in a meaningful and practical way. I spend a lot of time getting students to build numbers on these frames then eventually transfer these 'pictures' in 2D form, that is, they use numbers and signs to record their sentences. e.g. 

When students understand the relationship of these facts and the signs learning number facts would be so much easier.
