In This Task…
Students will explore teen numbers as being 10 and some more.
Intentionality…
In this task, students will compose teen numbers by seeing them as ten and some more. Teen numbers are the first double digit numbers that students use and are a transitional phase to understand our base ten system of numbers. The place value system demonstrates that the teen numbers are composed of a ten and some ones.
Big ideas of the unit:
- Understanding hierarchical inclusion allows for flexible composing and decomposing of numbers
- Place value in relation to teen numbers
- Addition names the whole in terms of the parts: when the parts of a set are known we call it addition
- Different addition situations will elicit different strategies
- Number relationships provide the foundation for strategies to help students remember basic facts
- Commutative and Associative property of addition can be used to help learn facts
- Models can be used to connect concrete to abstract

What Do You Notice? What Do You Wonder?
Show students the following video and share the following prompt:
Then, ask students:
What do you notice?
What do you wonder?
Allow students some time to think about what they just watched. They can turn and talk to a neighbour for 60 seconds and then allow them to share with the entire group. Be sure to write down these noticings and wonderings on the blackboard/whiteboard, chart paper, or some other means to ensure students know that their voice is acknowledged and appreciated.
Some of the noticing and wondering that may come up includes:
- I notice a bowling ball hitting some bowling pins.
- I notice that some pins did not fall down.
- I notice that the player threw a strike.
- I notice that some pins fell over from another lane.
- I wonder how many pins fell.
- I wonder how many pins are still standing.
