Pupil outcome: I can calculate change when purchasing more than one item. Key learning points: - Calculating change can be thought of as finding the difference between the cost and the amount of money given. - If you are buying several...

Pupil outcome: I can explain how using the same difference rule can make written calculations easier. Key learning points: - It is easier to use a written strategy for subtraction when no exchanging is required. - If the minuend and...

Pupil outcome: I can subtract numbers below 10 using efficient strategies. Key learning points: - When the subtrahend is bigger than the ones value of the minuend, we will have to bridge through 10 - Composition of numbers to 10 allows...

Pupil outcome: I can use column subtraction to subtract from a 2- or 3-digit number. Key learning points: - Start by subtracting the number with the smallest place value. - The minuend appears first in a column subtraction. - The...

Pupil outcome: I can subtract fractions with the same denominator. Key learning points: - If 5 subtract 2 is equal to 3 then 5 one sevenths subtract 2 one sevenths is equal to 3 one sevenths. - To subtract fractions with the same...

Pupil outcome: I can subtract to and from 10. Key learning points: - When the minuend has the same number of ones as the value of the subtrahend, the difference is 10 - Number pairs to 10 allow us to work out the difference from the...

Pupil outcome: I can understand the relationship between addition and subtraction. Key learning points: - Equations can be represented using part-part-whole or bar models - The sum in an addition and the minuend in a subtraction both...

Pupil outcome: I can solve problems using addition and subtraction, including bridging through ten. Key learning points: - Different subtraction calculations need different strategies. - Different addition calculations need different...

Pupil outcome: I can subtract 3-digit multiples of 10 by finding the difference between them. Key learning points: - When numbers are close together, the difference between them is small. - Finding the difference means we count on from...

Pupil outcome: I can use addition and subtraction strategies to solve problems in different contexts. Key learning points: - By looking carefully at the numbers involved, you can choose the most efficient strategy. - When numbers are...

Pupil outcome: I can use number facts to 20 to subtract multiples of 10 and bridge 100. Key learning points: - The language of unitising helps us to use number facts to 20 to subtract multiples of 10 crossing the hundreds. - If 14...

Mr. Addit solves subtraction problems that require him to trade first or regroup to solve.

Mr. Addit teaches how to solve subtraction problem without regrouping and check them with addition.

“Counting Up to Subtract” demonstrates how to use the counting up strategy to subtract within 20.

A video entitled “Subtract with a Number Line” describes ways to solve subtraction problems using a number line.

Subtraction using base-ten blocks with regrouping.

In this video, the teacher explains how to use a bar model to represent and solve subtraction equations. The example used is about a student named Jerome who lost 15 pencils and currently has 33 pencils. By creating a bar model and...

Subtract two integers.

Rules of subtraction.

In this lesson, students will learn how to assess the reasonableness of subtraction problems by using rounding. By rounding the numbers to the leftmost digit and subtracting, students can determine if the given answer is reasonable or not.

This video explains how to subtract decimals using the standard algorithm. It covers important concepts like lining up decimals and place values, regrouping, and the importance of placeholders.
