Addition Learning

Addition is a process which children learn quite naturally as soon as they learn to start counting. During kindergarten and first grade, adding piles of objects together is really important and reinforces childrens understanding of place value and 1:1 correspondence.

Later on, when children are confident adding piles of objects together, they can progress on to number lines or counting on in their heads. When children have understood this, they can begin to learn their addition facts and progress on to column addition. At 4th and 5th grade level, they start adding decimals.

Knowing your addition facts is still a key skill that children need to be able to use in real life math - you may not always have a pencil and paper to hand to do your column addition, but you will always have your addition facts!

Column Addition starts properly once children reach 1st grade, and after they have a good understanding of counting and place value. At first grade, children learn to add numbers up to 100 together.

Once they have mastered this, they can progress on to adding a range of 3 digit, then 4 digit numbers together in columns.

Once they reach 4th and 5th grade, they learn to add together columns of numbers which include decimals up to 2 decimal places.

What do children learn in KS1 maths?

In Key Stage 1 (KS1), kids explore a wide breath of content to help develop their knowledge of core concepts and gain an understanding of how maths is used in everyday life. From fractions to shapes, they learn lots of key skills that’ll place them in great stead for KS2!  The main topics they learn about are…    

1. Number and place value: In the KS1 maths curriculum, children learn to count, read, write and represent numbers up to 100. They also learn how to compare numbers and use the place value system.  

2. Addition and subtraction: Children learn various strategies for mental and written addition and subtraction. They also explore number bonds, counting techniques and inverse operations.  

3. Multiplication and division: Kids develop their understanding of multiplication and division and learn how to solve problems using multiplication and division facts, arrays and pictorial representations.  

4. Fractions : Learners discover how to recognise, name, find and write fractions in relation to length, shapes and quantity.

  5. Measurement: In KS1 maths, children learn how to use appropriate units, estimate measurements and read scales, including length, capacity and time.  

6. Properties of shapes: Learners explore the fundamentals of shapes, including how to recognise and name different types of 2D and 3D shapes.  

7. Position and direction: Children  learn how to describe position, direction and movement, as well as how to organise objects into patterns and sequences. 

8. Statistics: In the KS1 curriculum, kids explore how to collect and organise data. They also learn how to create graphs and interpret data using a variety of graphs.

There are lots of ways that you can help your child or pupils to learn KS1 maths:

• Rather than explaining concepts, use visual representations to explore them, such as number lines and grids.
• Nothing beats doodling! Encourage your child or pupils to draw pictures to help them understand concepts or have a go at working out the answer to a question. 
• Use real-life items to explore number, such as Smarties or pebbles. Encourage your child to sort the items into different amounts; doing this will help them understand concepts such as addition and fractions!
• Boosting their instant recall skills will help them with their mental maths and speed answering questions. Learning times tables in a specific order and using fun activities is a great way to help with this!

An array is an arrangement of items (such as pictures or numbers) in columns or rows.

They let children visualise what happens when they multiply or divide numbers together, helping them master times tables and division!

Reasoning is basically detective work: it’s when learners use what they already know to work out the answer to a question.

For example, if a child knows what 12 – 5 is, they can use this knowledge to work out what 12 – 6 is.

“I know that 12 – 5 is 7. As 6 is 1 higher than 5, the answer must be 1 higher than 7.”
