Students complete a table then describe and write a rule to work out the number of matchsticks needed to make alien shape patterns.

Students show how to work out the number of 1-digit that there are in 2-digit numbers.

Students show how to calculate maths problems involving fractions as a part and as a whole.

Students use percentages to calculate heights of a building from the total height. They then explain how to calculate another percentage.

This task requires students to estimate some addition problems using any appropriate method.

Students convert heights of a building into the percentage of the given total height, explaining how they solved some conversions. Assessment focus is on how they calculate these heights and what strategies they use.

In this task students decide which people are estimating and which are not, and explain their reasoning.

Students use the commutative property to find missing numbers in equations and explain the property.

Students identify multiples of 5 and of 3, and explain their reasoning.

Students predict the outcome of throwing five dice and confirm their predictions by conducting an experiment and calculating probabilities. After discussing how to get better estimates, they pool their results with others to get a more accurate estimate of how good their predictions were.

Students decide which statement about a dot plot is incorrect and explain their reasoning.

This task requires students to estimate some addition problems using any appropriate method.

Students estimate a multiplication problem, share their methods, discuss the rounding method, and then do more estimation problems using rounding.

Students estimate a multiplication problem, share their methods, discuss the front-end method, and then do more problems using front-end.

In this task students decide which people are estimating and which are not, and explain their reasoning.

This task requires students to show how to estimate numbers of items in some multiplication problems using any acceptable estimation strategy.

Students use the commutative property to find missing numbers in equations and explain the property.

Students decide which children are estimating and which are not, and explain their reasoning.

Students find the unknown for a range of equations that require number property knowledge and understanding of relational thinking.

Students identify the shaded fraction of a number of different shapes.

Students recognise equal and different likelihoods when playing a game of chance and explain their reasoning.

Students compare the overall distribution of two graphs and describe their reasons.

Students find subsequent shapes in a repeated pattern and show how to work out another shape based further on in the pattern.

Students write number sentences for story problems, and create story problems from number sentences.

Students find subsequent shapes in several patterns and show how to work out another shape based further on in the pattern.
