Faded 89

My memory has faded along with the paint on this old barn . What do you call the piece of wood used to close the door?

Fraction Man Part Two

Today I was subbing for a Grade 2 class. They were doing fractions in math and I noticed that there were 16 students in the class. We talked about a set of fractions. We divided the class into 2 groups of 8 and ttalked about 1 group bieng 1/2 of the class. Then we divide the class into 4 groups and finally 8 groups.

Then we looked at fractions of area. Each student took a piece of paper and we folded and unfolded it looking at halves, quarters, eighths and sixteenths.

Then the class made 2 fraction men. We divided up the tasks and I was very pleased with the results.

Equivalent Fractions

Introduce 1/3/, 2/6 and 4/12 as equivalent fractions in grade 3. Use egg cartons to hold 12 objects.


When 1/4 of grade 8 students think the answer to this question is 1/4 ......
I noticed in my reading today that some people are saying that fractions need to be taught as early as grade 1 and others are saying that they shouldn't be taught in elementary at all.

Grade 5 Fraction interviews

January 3 Today I spent some time working on interview questions. To see if the student understands fractions on a number line ask them to show you 0.5m. , 0.25 m and 0.755m on a meter stick.

Using pen and paper ask a student to add 0.4 and 3.

On a piece of graph paper, ask the student to draw a 3x 5 rectangle and shade in 1/3.
