KS2 Primary Maths Age 9-13 - Geometry: Translation - Explained

The video tutorial explains how to translate a triangle from position A to position B on a grid. It details the process of determining the number of squares the triangle moves to the right and down. The tutorial emphasizes careful counting of the gaps between squares to avoid errors. The final answer is provided, along with tips for accurate counting.

What is the initial task when translating a triangle from position A to position B?

• Determine the color of the triangle

• Calculate the area of the triangle

• Measure the angles of the triangle

• Find out how many squares it moves to the right and down

How many squares does the triangle move to the right?

• 4 squares

• 5 squares

• 6 squares

• 7 squares

What should you do after determining the horizontal movement of the triangle?

• Erase the original position

• Change the shape of the triangle

• Put a dot to mark the new position

• Calculate the perimeter of the triangle

How many squares does the triangle move down?

• 6 squares

• 5 squares

• 4 squares

• 3 squares

What is important to remember when counting the squares moved?

• Count only the corners

• Count the lines, not the gaps

• Count the gaps between the squares

• Count the squares twice
