Almost every day, the students take laps around the triangle outside our classroom door. This week, I wanted to know the perimeter of the triangle. I asked Teacher Elyse to take a few kids out with yard sticks and chalk to measure it. It turns out that that the perimeter was 140 yards. I showed the kids how to convert the yards to feet. Then, we used fractions to figure out how many miles one lap equaled. It turns out that one lap was 8/100 of a lap. From this calculation we were able to figure out that it would take 12 1/2 laps to equal 1 mile. Now we can start keeping track of how many miles we run each week. Neat!

We will be starting our first week back from Spring Break studying PERIMETER. Please watch this catchy video that helps explain the differences between AREA & PERIMETER. Please click here to go to the video. Thanks for watching! We use learning targets to set goals for our daily learning. By the end of the unit your child should be able to show understanding of the following learning targets. The targets are written from the perspective of the student in student friendly language.
I can find the area of a shape using unit squares. I can find the area of a rectangle using multiplication. I can find the perimeter of a polygon. I can find the missing side of a polygon. I can draw two rectangles with the same area and different perimeters. I can draw two rectangles with the same perimeter and different areas. I can find the area of a complex shape made of rectangles. I can classify quadrilaterals using attributes: · Rhombus · Rectangle · Square · Parallelogram · Trapezoid · Kite Great job with fraction kids! Our newest unit covers area, perimeter, classifying quadrilaterals, and much more. Watch this video to familiarize yourself with some of the geometry vocabulary we will be using. The creator of the video made some typographical errors, can you find them all? Click here to check it out.
We did it! We met our class goal. ALL of the students moved up a level from their pre-test scores. This Friday we will celebrate by enjoying a movie and munching on some fresh popcorn! Way to go 3rd graders!
This week we are finishing up our fractions unit. The students will be taking their post-test on Friday.
The unit has covered the following concepts: · Making fractions · Comparing fractions · Using number lines to make and compare fractions · Identifying equivalent fractions · Identifying proper and improper fractions We have set a whole class goal to motivate us to improve our scores. If 85% of the students can move up one level we will have a movie party. If all students can move up one level from their pre-test score then we will have a popcorn and movie party. Please ask your child what their improvement goal is. Thanks! This week we started learning about equivalent fractions. I found this video helpful because it gives a nice overview on equivalent fractions. About halfway through it switches to a PBS show that helps explain how to make equivalent fractions.

Click here to try a design program that gives you practice making flags using fractions. This is an activity that can help improve your child's understanding of fractions through art. This could lead to a whole host of discussions. Ever thought about how many flags are split into thirds?
We are starting our fractions unit this week. Our focus for this week will be understanding how people use fractions, identifying the parts of a fraction, and representing fractions as part of a whole and part of a set. Please encourage your child to try this fun Fraction Matching Game. Click here to go to the site. Also, explore fractions at home by showing them how fractions are used in cooking, sewing and construction. What other ways do you use fractions?
This video helps explain how to do repeated subtraction using a number line. The problem begins with drawing a number line, starting with the dividend and then jumping back towards zero by the value of the divisor. Check it out by clicking here.
