- Show addition and subtraction of numbers up to 100. Give the student only tens and 9 ones.
- Make sets to illustrate multiplication.
- Illustrate place value and ordering of numbers to one thousand.
- Illustrate addition and subtraction with and without renaming.
- Make sets and rectangles to illustrate multiplication and division.
- Use the 100-flat to illustrate ways to make 100.
- Let the 100-flat represent the number of cents in $1 and use to illustrate addition and subtraction of money within $10.
- Illustrate part-whole and comparison by subtraction in word problems.
- Illustrate division and multiplication word problems.
- Illustrate quotient and remainder.
- Illustrate multiplication and division of 3-digit numbers by a 1-digit number.
- Show how multiplying and dividing tens and hundreds is related to multiplying and dividing ones. For example, use 9 units and show 9 ones divided by 3 gives 3 ones, then used 9 rods and show 9 tens divided by 3 gives 3 tens.
- Make rods of different lengths to create bar graphs.
- Illustrate addition and subtraction of compound units - the unit cube is 1 cm and the 100-flat is 1 m folded up and the 1000-cube is a km folded up.
- Let the 100-flat represent 1 whole. The 10-rod is one tenth and the unit cube is one hundredth. Use to illustrate decimals to hundredths, ordering of decimal numbers, and the four operations on decimals.
- Let the 100-flat represent 1 whole. The unit cube is 1%. Use to illustrate percentage and the relationship between percentage and fractions and decimals.
- Put ten 10-rods in a row to illustrate word problems using percentage. All ten rods represent the whole, which is a specific number. Use to show whether multiplication or division is needed in such problems as: If the whole is 500, then what value does each 1% piece have? What about 40%. If 40 units, or 40% represents 80, what does 15% represent?
