Lesson details
Key learning points
- By looking carefully at the numbers involved, you can choose the most efficient strategy.
- When numbers are close together, finding the difference is the most efficient strategy.
- Sometimes, we can use known addition facts to make finding the difference even more efficient.
Keywords
Bar chart - A bar chart uses rectangular bars to show different values.
Pictogram - A pictogram is a graph that uses pictures to represent information.
Table - A table has information arranged in rows and columns.
Common misconception
Children can often be overwhelmed by the amount of visual data they are presented with.
Expose children to graphical data as much as possible outside of maths lessons. Encourage children to make simple bar charts with cubes so they understand their formation and liken the searching for specific values to search and find books.
These questions are specific in their contexts but the aim is for children to be able to solve them in their heads. Try to remove any scaffolds as much as possible so the children can grow confidently in their selection of mental strategies and their execution. Praise those who can!
