This Week’s News

Earlier this week, students had a guest speaker, Mr. Johnson, who brought ancient artifacts from the time of Early Humans. In addition to reviewing pertinent facts about each of the Early Human groups students studied–Australopithecus, Homo Habilis, Homo Erectus, Neanderthal, Cro-Magnon, and Modern Humans Homo Sapiens, the presenter also had students solve a mystery about Ötzi the Iceman. Ötzi’s well-preserved body was discovered by hikers on September 19, 1991, in the remote mountains on the border of Austria and Italy. It was determined that the body was 5,300 years old. He was named Ötzi after the region in which he was discovered. During the presentations, the students’ job was to listen to evidence and solve the mystery of how Ötzi died. After learning about his weapons, clothing, and supplies that were laid out by his body, students determined that the most likely scenario was either that Ötzi had been traveling with a partner and both were murdered by an enemy group or that a political rival, perhaps Ötzi’s brother, murdered Ötzi to gain power.

CPM Tip of the Week for Parents

Week 7

There are several types of problems your student sees when doing the classwork and the homework. The classwork problems have been designed to encourage students to work together with their teammates to solve interesting and challenging problems (with teacher support). At times, these problems require students to use previous learning. Some problems will require the use of manipulatives, such as blocks, number cubes, Algebra Tiles, or models to help develop understanding. Other problems introduce students to new ideas. All of the problems have been carefully constructed to further a student’s understanding of mathematics.

The homework problems are both for review and preview. Often the first problem or two will cover the work that was done in class that day. Then there are problems that review concepts from previous courses or lessons. There are also problems that are designed to prompt students to think about a mathematical idea that will be introduced in a future lesson. If your student is struggling with homework, suggest checking the CPM online Homework Help and other resources found at

For Students:

Showing Work

When doing math problems, it is important to show your work in an organized fashion.  Try jotting down information about the problem and possibly drawing a diagram first so that you can look back at your paper and know what the problem is about.  Then show all steps so that you’ll have an example to look at later.  Showing all steps is one way to justify your answer.  Make sure that your answer is easy to see and easy to find.
