What makes a number even or odd

I can tell whether a number is even or odd and explain why.

I can use drawings to share up to 10 things fairly among 2, 3, 4 or 6 friends, and compare the shares.

One third is the same as two sixths

I can show that one third and two sixths of the same whole are the same amount, and that two thirds and four sixths are too.

Properties of addition and subtraction

I can use the rules of adding and subtracting to make sums easier and to check my answers.

Addition and subtraction facts to 20

I can quickly say addition facts with totals up to 20 and the subtraction facts that go with them.

Mental math to add and subtract within 50

I can add and subtract numbers that total up to 50 in my head, estimate to check, and explain my strategy.

Adding-to and taking-away stories to 100

I can show and solve stories where some are added to a group or taken away, with numbers up to 100, whatever number is missing.

Putting-together and comparing stories to 100

I can show and solve stories that put groups together or compare two groups, with numbers up to 100.

Multiplication as repeated equal groups

I can show multiplication as equal groups put together again and again, including groups of one half and one fourth, and solve problems with it.

Division as sharing up to 12 items equally

I can show division as sharing up to 12 things equally, or as making equal groups, and solve problems with tools and drawings.

Repeated addition and subtraction for multiplying and dividing

I can use repeated addition to multiply and divide, use repeated subtraction to divide, and check multiplying and dividing with them.

Spotting patterns in geometric designs

I can find and describe patterns in geometric designs, including designs that repeat, grow or shrink.

Making and re-showing patterns with shapes and numbers

I can make patterns with shapes and numbers and show the same pattern another way, including growing patterns.

Finding the pattern rule to extend and predict with shapes and numbers

I can find the rule of a pattern made with shapes or numbers and use it to extend the pattern in any direction, predict and fill in missing parts.

Using patterns to show how numbers to 100 relate

I can make and describe number patterns that show how numbers up to 100 are related, going up and going down.

Noticing when a symbol is a variable

I can tell when a symbol stands for a number, whether it is one missing number or a number that can change, and say how it is being used.

Making addition and subtraction expressions equal

I can find what to add or subtract to make two addition or subtraction expressions equal, and show it with = or ≠.

Finding equal ways to make the same number to 100

I can find and use different ways of making the same number up to 100, and use them to make adding easier.

Writing and running code with things happening at the same time

I can write and run code where some events happen one after another and some happen at the same time.

Reading and changing code with things happening at the same time

I can read code with steps in order and steps at the same time, predict what it does, change it, and explain how the change affects what happens.

Sorting data by two features with Venn and Carroll diagrams

I can sort data about people or things by two attributes, using a Venn diagram, a Carroll diagram and a table.

Collecting data about two things and using two-way tally tables

I can collect data about two pieces of information by watching, trying things out or asking, and organize it in a two-way tally table.

Showing data with line plots and bar graphs

I can show data in concrete graphs, pictographs, line plots and bar graphs, one mark or square for each piece of data, with a source, a title and labels.

Finding the mode of a data set

I can find the mode of a data set, or say there are two modes or none, and explain what the mode tells about the data.

Asking and answering questions about data in logic diagrams, line plots, and bar graphs

I can read Venn and Carroll diagrams, line plots and bar graphs, ask and answer questions about them, and use the data to make a decision.

Describing likelihood, including events that cannot both happen

I can describe how likely events are with impossible, possible and certain, explain pairs of events that cannot happen at the same time, and use that to predict.

Predicting if the mode will match in a different group

I can predict whether the mode of data from one group will be the same for another group, test my prediction, and explain the result.

Sorting 2D shapes by sides and angles

I can sort and name 2D shapes by their number of sides, their side lengths, their angles and whether any sides are parallel.

Lines of symmetry in 2D shapes

I can find and count the lines of symmetry of 2D shapes, and sort shapes by how many lines of symmetry they have.

Building and breaking apart shapes without changing their area

I can build shapes from smaller shapes, break shapes into smaller shapes, and show that rearranging the pieces does not change the area.

Checking if shapes match exactly (congruent)

I can decide whether two shapes are congruent by matching their sides and angles, by moving them or by picturing them.

Making and reading simple maps

I can make a simple map of a familiar place from above, with a key, and read maps other people make, including maps on a grid.

Describing where several things are and how to move between them

I can describe where several objects are compared to each other and the moves needed to get from one object to another.

Measuring length with non-standard units

I can measure lengths with units like paper clips or cubes, choose a good unit, and explain why a smaller unit gives a bigger count.

Centimetres and metres, with benchmarks to estimate

I can explain that 100 centimetres make 1 metre, and use benchmarks for a centimetre and a metre to estimate lengths.

Measuring and drawing lengths in centimetres and metres

I can measure and draw lengths in centimetres and metres with a ruler, a metre stick or a tape, and find a length when I start at a number other than zero.

Describing how long something takes using units of time

I can describe how long an event lasts using seconds, minutes, hours and units like claps or sand-timer turns.

Making the same amount of cents with different coins

I can show the same amount of money up to 200 cents with different combinations of coins.

Making the same dollar amount with coins and bills

I can show the same amount of money up to $200 with different combinations of $1 and $2 coins and $5, $10, $20, $50 and $100 bills.
