Students often have to draw their own ray and mark specific points like Page 5: Comparing and Ordering Students use the ray to solve inequalities. Logic: If point is to the left of point , then the coordinate of is less than Example: because 5 comes before 8 on the ray. Page 6-7: Movement along the Ray While versions vary by edition, often asks students
Moving by intervals (e.g., jumping by 2s or 5s) which prepares students for multiplication later in the year. 📝 Breakdown of Key Exercises Page 4: Introduction to the Number Ray The focus is on the origin point (0) and the unit segment . Logic: If point is to the left of
