How can I teach my students to break apart arrays?
If students are more independent, or if you want to use this as seat work, simply print off this tutorial PDF for each student. (This is also found on the first page in the Array Break Apart Worksheet packet.) You can also show them how this looks as an equation: 6 X (2 + 4) = 36 OR (6 X 2) + (6 X 4) = 36.
How to break an array into multiples?
(This is also found on the first page in the Array Break Apart Worksheet packet.) You can also show them how this looks as an equation: 6 X (2 + 4) = 36 OR (6 X 2) + (6 X 4) = 36. Now, further the inquiry by asking students to list the other ways this 6 X 6 array can be displayed. See how many each student/group can find!
How do you break train of cubes apart?
