I made this worksheet as an accountability piece to use with the Lakeshore Learning number locks. It is a front and back worksheet of numbers 1-10 and numbers 11-20. There are two different worksheets so that you can differentiate. Students are supposed to find the matching number lock and write the number word on the dotted line as well as trace the number they found.
The number locks have keys with a number written on them, and students need to find the matching lock which will have the matching number of stars on one side and the number word on the other side of the lock. If it is a correct match the key will unlock the lock.
