Recommended Age: 5 years and onwards (can be younger depending on the child’s skills and experiences)
Purpose: To present the entire structure of addition and to help the child memorise the addition combinations
Level of Parent Involvement: Medium, the adult must present this exercise to the child, once the child has been shown they may work independently
Prerequisites
- The child must be able to count accurately from 1-10 and onwards
- The child must be able to write numbers
- The child must be able to match the numeral symbol with its quantity of numbers 1-10 and beyond
- The child must have had many experiences doing addition with the golden beads
- The child has been presented to the first, second and third presentations of the addition strip board (see activity library)
Materials
* Blue strips 1 to 9
* Red strips with partitions 1 to 9
* Pencil
* Small pieces of blank paper
* Ruler
* Control chart 2
NOTE; if doing this exercise with your child from home you will be using the paper version from your resource pack
Preparation
- None
Steps
- Invite the child together bringing the materials to the table
- Invite the child to choose their favourite number (for example 12) and write it on the paper
- Then invite the child to make that number as many ways as they can as per presentation 3 (using the example of 12 again)
- Once the child has made the number as many ways as they can, the child writes down all equations
- Then say to the child “how many ways did you make 12? lets read them”
- Together with the child read the equations, drawing the child’s attention to sums that are the same (9+3 and 3+9) by saying “I heard you read that before”, move the strips for that equation down to the bottom of the board (see image below)
- Show the child how to use the ruler to rule a line across the sum, repeat for other equations that are the same
- Then say to the child “now how many ways do you have?”
- Introduce control chart 2 and invite child to check equations
- Invite the child to choose another number to work independently with “how many ways”, the child may cross out
Variations
- None
