Comparison Sum and Difference

Diving into Mastery Guidance for Educators
Each activity sheet is split into three sections, diving, deeper and deepest, which are represented by the following icons:
These carefully designed activities take your children through a learning journey, initially ensuring they are fluent with the key concept being taught; then applying this to a range of reasoning and problem-solving activities.
These sheets might not necessarily be used in a linear way. Some children might begin at the ‘Deeper’ section and in fact, others may ‘dive straight in’ to the ‘Deepest’ section if they have already mastered the skill and are applying this to show their depth of understanding.

Aim
Solve comparison, sum and difference problems using information presented in bar charts, pictograms, tables and other graphs.
