Unit 1 · 5 skills

Number

Counting and Making Numbers to 20

Adding, Taking Away, and Change

Equal and Not Equal

The official wording · 5 outcomes
1.1
number concepts to 20
1.2
ways to make 10
1.3
addition and subtraction to 20 (understanding of operation and process)
1.4
change in quantity to 20, concretely and verbally
1.5
meaning of equality and inequality

Key ideas

  1. Touch each thing ONE time and say one number in order: 1, 2, 3… up to 20. The last number tells how many.

  2. Adding means putting groups together and counting how many in all.

  3. Equal means the same amount on both sides — a balance stays level.

  4. A number like 14 is one full group of ten and four more ones.

  5. Subtracting means taking some away and counting how many are left. Adding and taking away are opposite moves.

Watch out for

  • Skipping a number or counting one thing twice when things are scattered.
  • Starting the count over at 1 instead of counting on from the first number.
  • Thinking a longer or more spread-out row must have more, even when the count is the same.

Unit 2 · 1 skill

Patterns

Patterns That Repeat

The official wording · 1 outcomes
2.1
repeating patterns with multiple elements and attributes

Key ideas

  1. The 'core' is the small part that repeats over and over.

  2. Patterns can change more than one thing at once — like colour AND size together.

Watch out for

  • Only looking at colour and missing that size or shape is also changing.
  • Guessing what comes next without finding the repeating core first.

Unit 3 · 1 skill

Measurement

Measuring with Small Units

The official wording · 1 outcomes
3.1
direct measurement with non-standard units

Key ideas

  1. Lay units (like paperclips) end to end with NO gaps and NO overlaps, then count them.

  2. Use the same-size unit the whole time so the measure is fair.

Watch out for

  • Leaving gaps or overlapping the units so the count is wrong.
  • Mixing big and small units in the same measurement.

Unit 4 · 1 skill

Geometry

Flat Shapes and Solid Objects

The official wording · 1 outcomes
4.1
comparison of 2D shapes and 3D objects

Key ideas

  1. Flat (2D) shapes — circle, square, triangle, rectangle — have sides and corners.

  2. Solid (3D) objects — ball, box, can, cone — have faces you can touch and can be stacked or rolled.

Watch out for

  • Calling a solid object by a flat shape name (calling a ball a 'circle').
  • Sorting by colour or size instead of by shape.

Unit 5 · 2 skills

Data and Likelihood

Showing Answers in a Graph

Will It Happen?

The official wording · 2 outcomes
5.1
concrete graphs, using one-to-one correspondence
5.2
likelihood of familiar life events, using comparative language

Key ideas

  1. Use ONE block or sticker for each answer — that is one-to-one.

  2. Likely means it will probably happen; unlikely means it probably will not.

  3. The tallest stack got the most; the shortest got the least.

  4. We use comparing words: more likely, less likely, always, never.

Watch out for

  • Using more than one block for a single answer, so the graph is unfair.
  • Thinking 'unlikely' means 'impossible' — unlikely things can still sometimes happen.
  • Thinking the widest pile has more instead of counting the stack.

Unit 6 · 1 skill

Financial Literacy

Coins and What They Are Worth

The official wording · 1 outcomes
6.1
financial literacy: values of coins, and monetary exchanges

Key ideas

  1. Canadian coins have set values: a nickel is 5¢, a dime is 10¢, a quarter is 25¢, a loonie is $1.

  2. A fair exchange trades coins worth the same amount — two nickels (5¢ + 5¢) for one dime (10¢).

Watch out for

  • Thinking the bigger coin is always worth more (a dime is smaller than a nickel but worth more).
  • Thinking a trade is fair just because the number of coins is the same.
