Miquon math orange book, pages E-8 to E-9, and A-10 through A-12

Megan did pages E-8 and E-9, dealing with math addition families, 3, 4, and 7 and 5, 3 and 8. She also did page A-10 and A-11.  On these pages we talked about the number line and on page A-12, we discussed how different number lines can have different distances between the number, but on the same number line, the distant should be the same.
