This set of resources contains sample Number Talk lessons. Lesson 1 builds addition fluency using double ten-frames by making ten and adding more. Lesson 2 builds addition fluency with equations by making ten and adding more. Lesson 3 uses dot cards as representations of numbers to build math language as well as fluency with decomposing numbers within 10.

This resource is from Tools4NCTeachers.In this lesson, students analyze a picture of animals in the barnyard. Students use the context to create both addends unknown combinations to make 10. They show their thinking and record their decompositions using objects, words or drawings.Please remix this lesson to share your ideas for other problems, extensions, related math stations, or samples of student work.
