Teachers can model with their students how to Add On using a Number Line for sums to 20. There are a variety of suggested ideas with this resource.
Teachers can model during a mini-lesson how to add on. The resource can be printed or projected for this type of lesson.
Then the resource has 12 more guided lessons but their is less given information on the slides, allowing students to take over more of the thinking required to do the work.
As students gain more understanding they can move into the 28 guided center cards.
Students can also be given a caterpillar number line to use to solve any of the 72 equation cards. This could be done independently or as a guided math group activity.
Finally there are 2 student response pages that students could complete as further practice or as an assessment of their understanding of the topic.
I hope you and your students enjoy using this math resource and I hope it helps them grow in their math knowledge.
