Modeling Thinking ◆ 119The second frame to introduce is the 10 frame. The 10 frames are great
for teaching students the patterns of dividing 10s. For example, Sue had
30 marbles divided into groups of 10. How many groups did she have? Use the
10 frames to solve (see Figure 7.18).
Another frame that I like is the 7 frame. Sevens are notoriously dif-
ficult for students. So, use weekly pill boxes to have students solve prob-
lems from the 7 tables. For example, The bakery had boxed its cookies in
groups of 7. If they had 21 cookies, then how many boxes did they need? Use the
7 frames to model your thinking (see Figure 7.19).

Number Lines
Students should work often with number lines (see Figures 7.20, 7.21, 7.22,
7.23 and 7.28). They should have all types with various number ranges.
They should have some premade and some that they make. By second
