 Today students carried out another probability experiment. Students picked a colour tile from a bag, then replaced it. They repeated the process until they thought they could predict the colours of tiles in the bag based on the results of their picks. In this activity students:experience sampling with replacementinvestigate probabilitycollect and organize data (from Super Source Math)Below is the procedure for the action part of our math lesson:As a class, we tallied our results and our predictions. Students knew there were 10 tiles in the bag and some were green and some were yellow. From the results of their experiment (left hand columns), they made predictions on the number of green and yellow tiles in the bag (the right hand columns). In the bags, there were actually 3 green and 7 yellow tiles which was similar to the predictions students made based their experiment.
