Instructions for Use

Division Mine asks students to determine how to divide stones into groups so that they are shared equally. Note that the Medium level is most appropriate for students.

Select the Medium level, then click “Play.” Read the division problem and figure out how many stones would be in each group if they were shared equally. Click the answer below, then click “Close” to continue to the next problem.

Division Facts allows students to enter a division problem and then creates a model of the problem using arrays.

Click “New Problem” to begin. Choose a number between 1 and 81 to be divided. Type it  in the first box, then press “Enter.” Then follow the instructions to choose the number of groups, type it into the second box, then press “Enter.” Click “Divide” to watch the arrays be coloured differently to show the groups. Then click “New Problem” to try another division problem.

Division and Grouping (SMART Notebook-Compatible) allows students to practice dividing amounts of objects into equal groups. You should set this activity up for students. You may want to adapt the SMART Notebook file to suit your class.

Follow the directions on each page to divide the objects into equal groups.
