I got an Echo Dot recently and was so impressed at how easy it was to use I decided to get one for my classroom. I decided to make activities that allow students to set individual goals for themselves and also check their work. Here is how it works...
1) Students set a goal for how many facts they can solve.
2) Students set a time limit.
3) Students follow the instructions on the paper and say "Alexa, set the timer for..."
4) Students begin to solve the addition/subtraction problems.
5) When the timer goes off students check their work by following the Alexa prompt, "Alexa, what is 2 + 2?
6) Students correct wrong answers and write down how many they got correct.
