Math Mock and More!

Last week, your child took the Grade 3 Math Mock. Today your child will be receiving Day 2 of the Math Mock. I am returning the Math Mock to you so that you have some information regarding your child’s performance on the exam. Please look over the exam in order to determine areas in which your  child may need extra practice.

Please SIGN and RETURN the exam tomorrow morning. We will continue to use it in class.

Each short answer is graded out of 2 points. Each extended response is graded out of 3 points. I have provided individual feedback on your child’s exam.

Here are some helpful hints for all students to work on:

  • children need to read the entire question and make sure they answer ALL PARTS of a question
  • students should underline the important information in each question
  • students should check their work for calculation errors
  • students should draw a diagram or create a chart to manage the information in multi-step problems

What do we know?       What are we trying to figure out?

In the next few weeks, we will be familiarizing ourselves with the types of questions on the exam. We will also be working toward writing clear and concise explanations for the extended response questions. Children will receive some test questions for homework as well. This work will happen naturally inside our Math Workshop while we continue our unit on Fractions.

This week, we explored a sharing context in which we established some equivalencies for one half. We noticed that 3 out of 6 pieces of chocolate bar would be equivalent to 5 out of 10 pieces of a same-sized chocolate bar.  1/2 is a landmark fraction, and extremely important for students’ ability to compare different fractions. Today we compared fractions, determining if each fraction was greater than, less than, or equal to 1/2. 

Students are using notation for equivalence:

3/6=5/10= 8/16= 1/2

Students are also using notation to show inequality:

3/9 < 1/2

7/8 > 1/2

We will continue to explore different models for fractions when we return, including fractions on a number line.

I hope you have a wonderful Spring Break!  See you on April 9th!
