Expanded Notation Masters

The following links are for one of two sets of expanded notation cards. Run the masters off on card stock, and with a little time at a paper cutter, you will have sets for use in the classroom. These are used when counting very large collections of objects like 'pop tabs,' or in conjunction with place value dice. The use of the cards (and dice) reinforce the full values within each place, how numbers are composed and decomposed by place, as well as to reinforce the social conventions of writing a multi-digit number.

Expanded Notation Cards: Large Size,  0-9000

Expanded Notation Cards: Table Size, 0-100,000

 

Subitizing Cards

The link below will take you to the Department of Education and Training, Victoria State Government in Australia. Some of the best subiziting cards (they spell subitising with an 's') and ten-frame masters that you can find are at that site. These cards begin at the simplest standard dice patterns to fairly sophisticated images. They are quite useful to use selectively in the upper grades as well as younger grades.

While you are there, scroll up and down for additional resource materials that you may find useful.
