Addition resources

Students work out the smallest and largest amounts of coins and notes in a piggy bank from statements about the number and type of money.

Students estimate the sum of a number of fractions.

Students add and subtract fractions to work out fractions of food.

Students answer questions involving adding and subtracting fractions of cake.

Students solve addition story problems involving numbers of different magnitude to explore their place value understanding.

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

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

Students display their knowledge of algorithms by filling in missing digits for some computations.

Students select from a range of given numbers to complete a 4 x 4 'addition number square' with given row and column totals.

Students write algebraic expressions which make equations true.

Students use number properties to solve problems without calculating.

Students show how they perform an addition and a subtraction problem, and write their own subtraction story problem.

Students explain why a range of students' answers to a maths problem are incorrect.

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

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

Students to show how they estimate in some addition problems.

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

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

Students estimate an addition problem, share their methods, discuss grouping nice numbers, and then do a problem using this method, then design a question showing how it uses the method.

In this practical task, students are to estimate the cost of meals ordered from a menu. The teacher reads out the meals and students show the steps in their estimations.

This practical task involves students making best estimates of sets of items and clearly demonstrating their method(s) of estimation.

Student solve addition problems where the missing value is located in different positions. This may mean that students transform the problem into a subtraction one. Students reflect on the easiest and hardest problems, and explain their choice.

For this NEMP task students performs a series of increasingly difficult addition problems presented in vertical algorithms.
