In this unit, students integrate their understanding of skip counting by 5s and 10s to support telling and writing time to the nearest five minutes. They expand their prior knowledge of telling time to the nearest half hour, hour, and counting by tens to include counting by fives. Applying the knowledge of counting by fives and tens to the clock equips students to be successful in the reallife situation of telling time.
Key Concepts:
 We can use skip counting by fives and tens to tell and write time on both analog and digital clocks.
Prior Knowledge Needed:
 Counting to 100 by ones and tens (Grade K, Unit 13) (K.CC.A.1)
 Telling and writing time to the nearest hour (Grade 1, Unit 5) (1.MD.B.3)
 Telling and writing time to the nearest half hour (Grade 1, Unit 10) (1.MD.B.3)
Units on the Horizon:
 Understanding three digit numbers (Grade 2, Unit 6) (2.NBT.A.2)
 Relating skip counting to mental addition and subtraction (Grade 2, Unit 8) (2.NBT.A.2)
 Solving addition and subtraction problems involving measurement (Grade 3, Unit 6) (3.MD.A.1)
