Making 10 to Subtract is an important skill for our primary learners. 10 becomes a benchmark number, which makes addition and subtraction a mental process. Initially, though, Making 10 to Subtract can be a tough skill. As we are guiding students to 10, it must be a hands-on process. Students must be given hands-on opportunities to break apart numbers, redistribute their placement on ten frames, and create new equations. Then, we move students to the semi-concrete, drawing and illustrating the process. Finally, students use numbers and number bonds to show their thinking. If students struggle with the semi-concrete or abstract stages of Making 10, then return to the concrete. Having a conceptual understanding of Making 10 is critical to true mastery. The resources in this download provide a variety of learning experiences for your students.

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
