Chapter 9  is about deveoping measurement concepts. Estimation of measurements is something students need to experience. It is also important that students practice using various units, sometimes even creating their own units. Everyday objects can be very helpful in measuring area, i.e. beans, color tiles, pennies. Using these objects can lead into measurement using standard units.

Algebraic reasoning is covered in Chapter 10. Patterns, symbols,  and number relationships are the basis of algebra. Students need to see that algebraic variables are just other ways to represent numbers.
