This powerpoint has animations--meaning the question is presented (about a relevant graph) and then the answer is shown on the teacher's click.
For example, on the screen there may be a picture, graph, and question. After the children answer the question, the teacher clicks and the answer is circled or appears (like the letter B beside the graph or if the question was asking an amount the number might present itself on the teacher click).
Very engaging! Fun for the kids. After we did this, then we collected data and made our own graphs.
