This lesson builds on counting skills using an upbeat musical song. This is a foundational kindergarten concept and provides experience with rote counting, rythmic beat, and visual number recognition. Â Students will begin to see the numeric patterning of numbers while singing the song.
The purpose of this task is to support students' reasoning based on place value to multiply a single digit number by a multiple of 10. This reasoning builds on and supports knowledge described in 2.NBT.A.1, 3.OA.A.1, and 3.OA.B.5. If used in an instructional setting, students might benefit from having access to base-ten blocks. Students should also be encouraged to use a number line marked with tens. An empty number line is an excellent tool that helps students who are ready to develop a more abstract understanding of place value but are not yet ready for a purely symbolic solution approach.
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 real-life situation of telling time.
