  7. Math Message Grade 4 Lesson 1.2 Read Student Reference Book, pages 88 and 89 with a partner. List 3 places where geometry can be found in our world.

  8. 1.2 Today’s FocusWe will learn about geometry tools and review the vocabulary – points, line segments, lines, and rays.

  9. 1.2 Math Vocabulary: Enter these words into your math journals. • point • line segment • endpoint • line • ray

  10. 1.2Ongoing LearningAddition Top-It – Develop instant recall of addition facts (SRB p.263)
