Short Division with 1 and 2 digit divisors,

The purpose of this week's lesson was to reinforce short division with 1 and 2 digit divisors. The algorithm has many steps but we focused on reducing risk.

For instance, if the children are dividing by 2, they should write down in the margins the first nine multiples of 2 such as 2,4,6,8,10,12,14,16,17,18.

If they are dividing by 7, they write down 7,14,21,28,35,42,49,56, and 63.

Now they follow the algorithm and steps on the attached pdfs.

Bendaroos: Numbers, Polygons and other Shapes

This week we had the children us Bendaroos to trace out numbers and shapes.

The categories of numbers are intended to encourage children to think of everything as number:

Dividing by 11 -- Short Division Method

All Even Digit Palindromes Are Evenly Divisible by 11. 

To prove that this statement is true, you will see the steps below to use my Short Divsion Method. After you get comfortable with the example, start to write down even digit palindromes and divide them by 11 to see that there is no remainder at the end.

Halving Paper

Students alway love to fold paper in half. They somehow understand that this creates a fraction of 1/2 even at the preschool level. But what happens when they fold it in half again? It creates four equal rectangles or a fraction of 1/4. What if they keep going?
