KS2 Primary Maths Age 9-13 - Algebra: - Explained

The video tutorial explains how to solve a grid puzzle where each shape represents a number. The goal is to find the number that replaces a question mark by determining the values of different shapes. The process involves solving equations for rows and columns to find the values of a triangle, cross, and arrow. The final step is to calculate the sum of these values to replace the question mark.

What is the main objective when analyzing the grid of shapes?

• To count the total number of shapes

• To rearrange the shapes in a specific order

• To determine the number each shape represents

• To find the color of each shape

How is the value of the triangle determined in the first row?

• By multiplying the cross shape value by 2

• By adding the cross shape value to 16

• By dividing the cross shape value by 2

• By subtracting the cross shape value from 16

What is the value of the cross shape?

• 5

• 6

• 7

• 4

How is the value of the arrow shape calculated?

• By dividing the cross shape value by 2

• By adding the cross shape value to 18

• By subtracting the cross shape value from 18

• By multiplying the cross shape value by 2

What is the final number that replaces the question mark?

• 15

• 18

• 17

• 16
