Good things come in threes, especially at the aquarium! Join Mia today as we learn to add three numbers together to find the total. Mostly, we've learned to add two numbers together, like 2+3, but today we are working with three charming...

In this math video we will learn the rules for adding rational numbers in decimal form. We will begin by reviewing the three steps to adding or subtracting decimals. We will line the decimal values up vertically using the decimal points....

The video demonstrates how to add three-digit numbers without drawing pictures but by using expanded form. The host explains how to expand each number and add the values of the hundreds, tens, and ones separately. The process is shown...

Pupil outcome: I can use my knowledge of number pairs to 10 to add three addends efficiently. Key learning points: - The order of the addends can change and the sum stays the same. - When adding three addends, it is efficient to first...

The video “Add Three Digits Number Line” demonstrates how to use a number line and knowledge of place value to solve addition equations with 2 addends that are each 3 digits.

In this video, the teacher demonstrates how to add three to four 2-digit numbers vertically by using the strategy of making 10s. Review real-world examples that emphasize the commutative property of addition.

👉 Learn how to add or subtract radicals. A radical is a number or an expression under the root symbol. Radicals can only be added or subtracted if the numbers or expressions under the roots are the same for all terms. To add or subtract...

👉 You will learn how to add and subtract numbers in decimal form. When adding and subtracting decimals it is very important to align the decimal points and use zero as space holders. Then you will apply the operations just like we do in...

Pupil outcome: I can use doubles and near doubles to add three numbers. Key learning points: - Addition of 3 addends can be described by an aggregation story with 3 parts. - Number facts to 10 can help to add three small numbers. -...

In this math video we will learn how to plot the solution on a number line to answer a standardized math test question. We will solve an equation by adding rational numbers. We will review the rule for adding number values with...

Pupil outcome: I can use a 'First, then, then, now' story to add three addends. Key learning points: - A 'First … then … then … now' story can represent an addition with three addends. - The addition of three addends can be represented...

Pupil outcome: I can choose the best strategy to add three small numbers together. Key learning points: - Using commutativity allows us to simplify a problem with three addends. - Using known facts allows us to add three addends...

Pupil outcome: I can recognise number pairs that total 10 and use them to find the sum of three numbers. Key learning points: - Rearranging the addends identifies the pairs that total 10. - Place value means we can add a single digit to...

Pupil outcome: I can add three addends efficiently. Key learning points: - The order of the addends can be changed to make the addition easier - The sum will be the same whichever pair of addends we add first. - Finding a known fact or...

👉 Learn how to add polynomials. To add polynomials, we first simplify the polynomials by removing all brackets. Then, we combine like terms. Like terms are terms that share the same base and power for each variable. When you have...

Pupil outcome: I can explain that the addends can be added in any order. Key learning points: - When we add three numbers, the sum will be the same whichever pair of addends we add first. - The order of the addends can change and the sum...

This video shows the process for answering questions on the SATs exam and is aimed at primary/elementary-level students. It also shows the process for solving the problem presented in SATs 2022 Paper 1 Q1, which involves adding three...

Pupil outcome: I can represent addition problems using ‘first, then, then, now’ and bar models. Key learning points: - Addition of three addends can be described with a first …, then …, then …, now structure. - A bar model can be used to...

Pupil outcome: I can multiply a 3-digit by a 1-digit number using expanded and short multiplication (no regroups). Key learning points: - Expanded multiplication of a 3-digit by a 1-digit number will give three numbers to add to...

Do you need to learn how to use a scientific calculator to add fractions? In this video, I will guide you through three fraction addition problems. I will show you how to enter both fractions and mixed numbers into a scientific...
