Unit 1 · 17 skills

I can start from a number I know and count on to find the total.

I can show a number as equal groups, sometimes with extra singles.
Official code: 1.N6
Comparing Sets and More or Less

I can model an adding or taking-away action and write it as a number sentence.
Official code: 1.N8
Counting on and counting back to add and subtract
I can count on or count back to find sums and differences.
Official code: 1.N9
Making 10 and using doubles
I can use making 10 and doubles to find sums.
Official code: 1.N9
Using addition to subtract
I can find a subtraction fact by thinking about addition.
Official code: 1.N9
The official wording · 17 outcomes
- 1.N1
- Say the number sequence, 0 to 100, by 1s forward and backward between any two given numbers
- 1.N1
- 2s to 20, forward starting at 0; and 5s and 10s to 100, forward starting at 0.
- 1.N2
- Recognize, at a glance, and name familiar arrangements of 1 to 10 objects or dots.
- 1.N3
- Demonstrate an understanding of counting by indicating that the last number said identifies “how many”; showing that any set has only one count
- 1.N3
- using the counting on strategy
- 1.N3
- and using parts or equal groups to count sets.
- 1.N4
- Represent and describe numbers to 20 concretely, pictorially and symbolically.
- 1.N6
- Demonstrate, concretely and pictorially, how a given number can be represented by a variety of equal groups with and without singles.
- 1.N5
- Compare sets containing up to 20 elements to solve problems using: referents
- 1.N5
- Compare sets containing up to 20 elements to solve problems using: referents; and one-to-one correspondence.
- 1.N7
- Identify the number, up to 20, that is one more, two more, one less and two less than a given number.
- 1.N8
- using familiar and mathematical language to describe additive and subtractive actions from their experience
- 1.N8
- creating and solving problems in context that involve addition and subtraction
- 1.N8
- and modelling addition and subtraction using a variety of concrete and visual representations, and recording the process symbolically.
- 1.N9
- Describe and use mental mathematics strategies (memorization not intended), such as: counting on and counting back
- 1.N9
- making 10; doubles
- 1.N9
- and using addition to subtract to determine the basic addition facts to 18 and related subtraction facts.
Key ideas
Counting forward means each number is one bigger; counting backward means each number is one smaller.
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, drawings, or a written numeral.
A referent is a known amount we compare a new set to.
Joining words like 'and,' 'more,' and 'altogether' describe adding.
Watch out for
- Skipping a number or saying two numbers at once while counting.
- Counting each dot instead of recognizing the whole pattern.
- Confusing teen numbers like 13 and 30 when saying them.

Patterns and Relations
Repeating Patterns
Describing repeating patterns
I can describe a repeating pattern and find the part that repeats.
Official code: 1.PR1
Copying, extending, and creating patterns
I can copy a pattern, keep it going, and make my own.
Official code: 1.PR1
Translating a pattern to a new form
I can show the same pattern in a new way.
Official code: 1.PR2
Equality as a Balance
Balance and imbalance
I can show when two sets are equal or not equal using a balance.
Official code: 1.PR3
The official wording · 4 outcomes
- 1.PR1
- Demonstrate an understanding of repeating patterns (two to four elements) by: describing
- 1.PR1
- reproducing; extending; and creating patterns using manipulatives, diagrams, sounds and actions.
- 1.PR2
- Translate repeating patterns from one representation to another.
- 1.PR3
- Describe equality as a balance and inequality as an imbalance, concretely and pictorially (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.
Patterns can be made of colours, shapes, sounds, or actions.
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.
- Calling a random sequence a pattern when nothing repeats.

Shape and Space
Measuring by Comparing
Comparing and ordering by an attribute
I can compare and order objects by an attribute like length or mass.
Official code: 1.SS1
Comparing by filling, covering, and matching
I can compare objects by filling, covering, or matching them.
Official code: 1.SS1
Sorting and Building Shapes
Sorting, comparing, and building shapes and objects
I can sort, compare, and build 3-D objects and 2-D shapes.
Official code: 1.SS2
The official wording · 3 outcomes
- 1.SS1
- Demonstrate an understanding of measurement as a process of comparing by: identifying attributes that can be compared; ordering objects; making statements of comparison
- 1.SS1
- and filling, covering or matching.
- 1.SS2
- Sort, compare, and construct 3D objects and 2D shapes
Key ideas
We can compare objects by length or by mass (how heavy they are).
We can sort shapes and objects by an attribute, like whether they roll or how many sides they have.
Statements like 'longer than' or 'heavier than' describe the comparison.
A 3-D object takes up space (a ball, a box); a 2-D shape is flat (a circle, a square).
Filling one container from another shows which holds more.
Watch out for
- Comparing by the wrong attribute (length instead of mass).
- Confusing a 3-D object (a ball) with a 2-D shape (a circle).
- Saying 'bigger' without naming which attribute.
