Homework Hello Students and Parents. We will continue learning about Angles this week. Students will relate degrees to fractional parts of a circle, they will use a protractor to measure and draw angles, and students will determine the measure of an angle separated into parts. There is a Quiz on sections 11.1-11.3 on Thursday January 21, 2015. The Chapter 11 Test is on Tuesday January 26, 2016. Please use the study guide to prepare for the test. i-ready All students need to complete 2 lessons of MATH i-ready per week for a grade. The 2 completed lessons of i-ready are due by Sunday night. Students must complete a quiz at the end of each i-ready lesson in order to receive credit for a completed lesson. Think Central - Students have access to Think Central which will help review Chapter 11. While the lessons are not mandatory, they are available for students who would like to review the material and prepare for the assessments. If your child is absent, Think Central is an excellent tool to review the lessons missed.
