Decimals
The big goal for this unit is for students to multiply and divide decimals as well as utilize mental math and estimation
PLACE VALUE
We began with place value as students need to understand where the numbers are coming from in order to use them in questions or real life.

MULTIPLYING ESTIMATION
In every question we do in the decimal unit, I would like students to estimate their answer prior to answering the question. This assists in their mental math and it also ensures they have placed their decimal in the correct place.

MULTIPLYING PICTORIALLY
The next step on our journey to multiplying decimals was to show their understanding concretely and pictorially (using arrays and base ten blocks)

MULTIPLYING SYMBOLICALLY
Now that students can use arrays and base ten blocks, students needed to give the actual mathematical representation a try. Here is a GREAT video on the how to.

DIVISION ESTIMATION
Use Front End Estimation and/or Rounding. Then make sure the number is the nearest whole number that is a multiple of the divisor.
DIVISION PICTORIALLY
The next step on our journey to dividing decimals was to show their understanding concretely and pictorially (base ten blocks and arrays)
How to divide decimals using base ten blocks
How to divide decimals using hundred grids
DIVISION SYMBOLICALLY
Now that students understood the necessity of splitting the numbers up into equal groups, students needed to give the actual mathematical representation a try.

STEPS FOR DIVISION WITH DECIMALS
1. Estimate
2. Place the decimal
3. Divide
4. Multiply
5. Subtract
6. Bring Down
**REPEAT STEPS 36 until you get zero from subtraction with no numbers remaining in the question to bring down
7. Check with multiplication
