We have worked on....
1. Standard form using the numerals
2. Word form where we write out the words. Students are learning to use a hyphen to connect the tens and the ones.
3. Expanded form is where we use the value of the numbers to create a number sentence. For example, 84 =80+4
4. Base ten models where we represent the number using tens rods and unit cubes.
5. Decomposing the numbers where we look at other combinations of tens and ones. Ex. 84 can be...
8 tens and 4 ones
7 tens and 14 ones
6 tens and 24 ones
5 tens and 34 ones
Etc...
