Maths topic: __Bar Graphs__ [Primary]

- Pupils are to catch the bugs and put them in the chart on the right.
- This is similar to organising the objects to form a picture graph. However, the bar chart will be automatically formed (and built on) once the bug is placed on the grid of the right colour.
- The activity can be used in the
__introduction__of bar graph, where they connect the prior knowledge (ie. Picture graph) to (learn) the new knowledge (ie. Bar graph). - Upon completion (for the 3 rooms), a question pops up to check pupils’ understanding/ interpretation of the graph (this could be the very first attempt pupils
__learn to interpret__a bar graph).
