Round whole numbers to the nearest ten or hundred.

Count to 1000, including by 50s, 100s and 200s.

Partial Skip counts by 5s, 10s and 100s. Does not cover 50s or 200s.

Use place value to describe multi-digit numbers, including with base ten materials.

Solve fair-share problems sharing up to 20 items among many sharers.

Solve fair-share problems that use equivalent fractions.

Use the properties of operations and the relationship between multiplication and division.

Recall the multiplication facts of 2, 5 and 10 and the related division facts.

Use mental math to add and subtract whole numbers up to 1000.

Understand the algorithms for adding and subtracting whole numbers.

Solve addition and subtraction problems with totals up to 1000.

Represent multiplication up to 10 × 10 and division up to 100 ÷ 10 using arrays.

Solve multiplication and division problems, including groups of a half or a third.

Connect the numerator of a fraction to repeated addition of the unit fraction.

Use the ratios 1 to 2, 1 to 5 and 1 to 10 to scale numbers up.

Partial Reads and writes the ratio. Does not use it to scale a quantity.

Identify repeating elements and operations in a variety of patterns.

Create and translate patterns using shapes, numbers and tables of values.

Partial Generates the pattern and plots it. Does not translate between representations.

Determine pattern rules and identify missing elements.

Create patterns that illustrate relationships among whole numbers up to 1000.

Describe how variables are used and use them in context.

Partial Evaluates an expression with a letter in it. Does not ask what a variable is for.

Determine whether sets of expressions in all four operations are equivalent.

Identify and use equivalent relationships for whole numbers up to 1000.

Display data in many-to-one pictographs and bar graphs with appropriate scales.

Determine the mean and identify the mode, and explain what each indicates.

Analyse data in frequency tables and in graphs with different scales.

Describe likelihood as impossible, unlikely, equally likely, likely or certain.

Sort cubes, prisms, pyramids, cylinders and cones by faces, edges and vertices.

Compose and decompose structures and identify the shapes they contain.

Identify congruent lengths, angles and faces of three-dimensional objects.

Partial Applies a rigid motion in the plane. Does not judge congruence of solids by matching.

Estimate, measure and compare the perimeters of polygons and curved shapes.

Explain the relationships between millimetres, centimetres, metres and kilometres.

Use non-standard units to estimate, measure and compare capacity.

Partial Reads a marked beaker. Does not use non-standard units or ask about overfilling.

Compare, estimate and measure mass using a pan balance and non-standard units.

Partial Reads a marked scale. Does not use a pan balance or non-standard units.

Measure one attribute with units of different sizes and compare the results.

Partial Measures with one unit. Does not ask why a different unit gives a different count.

Tell time in hours, minutes and seconds using analog and digital clocks.

Compare areas by matching, covering, or decomposing and recomposing shapes.

Use non-standard units to measure area and explain the effect of gaps and overlaps.

Partial Counts unit squares that tile exactly. Does not ask about gaps or overlaps.

Use square centimetres and square metres to estimate, measure and compare areas.

Estimate and calculate the change required for simple cash transactions.

Partial Works out the change exactly. The coins drawn are American: Canada has no penny and adds the loonie and toonie, so the values differ even though the skill does not.
