Key ideas
Counting forward means the numbers get bigger by one each time; counting backward means they get smaller by one.
Subitizing means knowing a small amount just by looking, like the dots on a die.
A number to 20 can be shown with counters, ten frames, or base-10 materials.
A referent is a known amount we compare a new set to.
One more means the next number up; one less means the number before.
Watch out for
- Skipping a number or saying two numbers at once when counting.
- Counting each dot instead of recognizing the whole pattern.
- Confusing teen numbers like 13 and 30 when reading.

Patterns and Relations
Repeating Patterns
Describing and extending repeating patterns
I can describe a repeating pattern and keep it going.
Official code: 1.PR.1
Copying and creating patterns
I can copy a pattern and make my own repeating pattern.
Official code: 1.PR.1

Balance and imbalance
I can show when two sets are equal or not equal using a balance.
Official code: 1.PR.3

I can write an equality using the equal sign.
Official code: 1.PR.4
The official wording · 5 outcomes
- 1.PR.1
- Demonstrate an understanding of repeating patterns (two to four elements) by n describing n extending patterns using manipulatives, diagrams, sounds, and actions.
- 1.PR.1
- Demonstrate an understanding of repeating patterns (two to four elements) by n reproducing n creating patterns using manipulatives, diagrams, sounds, and actions.
- 1.PR.2
- Translate repeating patterns from one representation to another.
- 1.PR.3
- Describe equality as a balance and inequality as an imbalance, concretely and pictorially (0 to 20).
- 1.PR.4
- Record equalities using the equal symbol (0 to 20).
Key ideas
A repeating pattern has a core that repeats, like red-blue-red-blue.
Two sets are equal when they balance, like a level see-saw.
Once we know the core, we can extend the pattern and spot missing parts.
When one side has more, the sets are unequal and the balance tips.
We can reproduce a pattern with different materials, keeping the same repeating core.
Watch out for
- Missing the exact core that repeats.
- Thinking a level balance can still have unequal amounts.
- Extending with the wrong element.

I can compare objects by an attribute like length or mass.
Official code: 1.SS.1

Building shapes from smaller shapes
I can build a bigger shape out of smaller shapes.
Official code: 1.SS.3
Finding flat shapes on solid objects
I can find flat shapes on solid objects around me.
Official code: 1.SS.4
The official wording · 5 outcomes
- 1.SS.1
- Demonstrate an understanding of measurement as a process of comparing by n identifying attributes that can be compared n ordering objects n making statements of comparison
- 1.SS.1
- Demonstrate an understanding of measurement as a process of comparing by n filling, covering, or matching
- 1.SS.2
- Sort 3-D objects and 2-D shapes using one attribute, and explain the sorting rule.
- 1.SS.3
- Replicate composite 2-D shapes and 3-D objects.
- 1.SS.4
- Compare 2-D shapes to parts of 3-D objects in the environment.
Key ideas
We can compare objects by length, mass, how much they hold, or area.
We can sort by one attribute, like colour, size, or number of sides.
Statements like 'longer than' or 'heavier than' describe the comparison.
The sorting rule tells why each item is in its group.
Filling one container from another shows which holds more.
Watch out for
- Comparing by the wrong attribute (length instead of mass).
- Switching the sorting rule partway through.
- Saying 'bigger' without naming which attribute.
