Number and Algebra resources

Students find fractions of numbers of different farm animals and put them in their simplest form.

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.

Students show how they solve equal sharing problems.

Students write down an explanation of how the front-end estimation strategy works in addition problems to give information on their understanding of the strategy.

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

Students estimate an addition problem, share their methods, discuss the rounding method, and then do more problems using rounding.

Students perform decimal multiplication and division involving the cost of material, without the use of a calculator.

Students use estimation strategies to calculate the number of vegetables they can buy with given amounts of money.

Students show or explain how two different fraction numbers can represent the same fraction.

Students show that they can picture the whole shape when given a fractional part.

Students compare fractions, identify which is larger, and explain or show their reasoning.
