# 3–6 multi-age, Year B – Unit 10

This 2-week, Year B unit develops the big idea that angles are the primary structural component of many shapes.

Students are provided opportunities to:

• measure, compare and sequence events by halving and quartering blocks of time
• represent fractional quantities of time and the multiplicative relationships
• estimate and describe the size of angles using known angles as benchmarks such as right angles
• estimate, measure and compare angles using degrees
• solve problems involving duration, using 12- and 24-hour time.
