**Welcome mathematicians and historians! **

Here you will find out what we will be learning for the week in math and social studies!

**Math**

Week of March 19th - March 23rd

Students will classify quadrilaterals using their attributes, draw lines of symmetry, and problem solve using a model. On Wednesday, students will take the Chapter 14 Geometry Cumulative Test. Students should go on the **Chapter 14 Geometry Blendspace** to review concepts and skills. On Thursday and Friday, students will review different skills and concepts taught from the beginning of the year in preparation for the GA Milestones.

**Chapter 14 Vocabulary Words**

**acute triangle** - a triangle that has 3 acute angles
