Ch.1 & 2 Test

You should be able to:

• Use quantitative anaylsis to solve problems (i.e. the trains approaching each other)
• Take a number and use place value to think about the number in different ways. (Similar to our discussion about money--$235 can be thought of as 235 ones, 23 1/2 tens or 2.35 hundreds, etc.)
• Work with bases other than ten: (a) take a base ten number and convert it to another base, (b) take a number from another base and convert to base ten, and (c) add and (d) subtract numbers that are in other bases.
