Objective: Use counting on and the make ten strategy when adding across a ten. (Day 2)
In Lesson 14, students use arrow notation to get to the next ten and then add the remaining amount when adding across ten. For example, when adding 28 + 6, students recognize that they started with 2 tens 8 ones and after adding 6, had 3 tens 4 ones. Students also use the bond notation from Module 2 to represent how they are breaking apart the second addend to make the ten (1.NBT.4).
