This is a fantastic resource for teaching rounding! This Stand Alone Instructional Resource teaches a complicated math subject and gently guides the user through rules, examples, and prompts. When a user chooses a wrong answer, there is an applicable prompt that further explains how to apply the rule. It also uses a visual aid that breaks down the rounding concepts into units, which I found to be very helpful. It is very thourough and clearly designed into three parts. There is a helpful rhyme that is used throughout the StAIR that reinforces the material presented.
3 answer slides need to be edited. And there was a spelling error on slide 61: "hundreds" --> "hundreths"
It was easy to navigate, had clear directions, and appropriate interactive buttons.
