We can divide $68$68 by $4$4 by drawing $68$68 dots in $4$4 rows.
a
To work this out we can count groups of $4$4 until we reach $68$68.
But that could take a long time if we go $1$1 group of $4$4 at a time, so let's count up in larger groups.
If we first count $10$10 groups of $4$4, how many dots will we have used?
| $\editable{}$ dots | |
| $4$4 rows |  |
| $68$68 dots |
b
How many dots are remaining when we take away the first $40$40?
| $40$40 dots | $\editable{}$ dots | |
| $4$4 rows |  |
|
| $68$68 dots | ||
c
How many columns of $4$4 dots will we have in the group of $28$28?
d
Here is the complete array.
| $10$10 columns | $7$7 columns | |
| $40$40 dots | $28$28 dots | |
| $4$4 rows | |
 |
| Total: $68$68 dots | ||
Using this, what is $68\div4$68÷4?
