Here's how math will happen: everyone gets an inventory test, to see where they are and what they need to learn/ know for Math. After that the Math lessons are taught from the textbook. We start with Geometry, as we visit Pythagoras, in Ancient Greece, and look at his right triangles. Students do the group lesson/classwork first. When they finish the group classwork, they are required to do the next thing in their individual math packets, which are based on their inventory tests. There will be a pre-test for each chapter. If a student scores 100% on the pre-test, that student gets to skip that chapter (classwork and homework), but must instead do/hand in the next chapter from their packet (based on their inventory test of what they needed to learn). The inventory test has no ceiling, I keep testing, until I find something new that your child can learn in Math. I love math! Math tests once a month, on the class lessons, with bonus questions from packets. Mathematics homework and will be on the Mathematics page. Math enrichment is on the Extension Activities Page.

Name That Number

Darby was playing a game of Name That Number. She had the following five number cards and target numbers:

Cards

Target

2, 3, 1, 4, 5                                                                      13

Her teacher, Mr. Diaz, asked everyone to record their thinking.

Here is what Darby wrote:

5 x 4 - 3 x2 +1= 13

5 x3 -4 x 1 +2 = 13

5 x4 / 2 -3 x 1 = 13

a. Mr. Diaz saw that Darby had made mistakes in writing two of her number sentences.

Circle the two number sentences with mistakes.

Explain in words how Darby can correct each number sentence. (Hint: The numbers are in the correct order).
