While Playing: 
  • Play the interactive Prime Radicals games with your child.
  • Take turns while you play and engage your child in dialogue to get them thinking critically about what they are doing while they are playing.
  • Playing together with your child helps to create meaningful connections that also serve to help your child be more successful in school in the future.
Ontario Curriculum Connections: 

Playing the interactive games on the Prime Radicals site, helps your child strengthen their math skills; specifically fractions, subtraction, addition and patterning and algebra. For more curriculum related information, click on the following link   This game meets many expectations in multiple grades, one of which is:

Math: Number Sense and Numeration

Demonstrate an understanding of magnitude by counting forwards and backwards by various numbers and from various starting points, and by fractional amounts.


At-Home Activities: 

There are many ways to bring math into your child's every day routine, in a way that is fun and easy!

  • When you go shopping with your child, point out the price tags, and any sale signs. Together work out how much something would cost if it were 50% off, or 25% off.
  • When cutting pizza at your house, or a pie, or anything that can be divided into pieces, engage in conversation about what you are doing. Ask questions like, "if there were 2 other people here, how many pieces would each person get?" or "what if 2 people wanted one more piece each, how many would be left over?"

How to Draw a Person

Most kids can draw stick people fairly easily, but drawing pictures of real people can be a bit tougher. This activity will teach kids how to draw realistic

pictures of people, just by using the oval. Here's how:

    Start by drawing an oval about the size you want a person's head to be, on a piece of paper. Then leave a space below the head for a neck (see drawing below for the correct proportions), and draw 7 more ovals in a line straight down. This will become the body – it works because everyone is about 8 of their own heads in height.

    Our trunk, or chest is about 2 heads tall. Create this by drawing a bigger oval that circles the first two ovals you drew vertically below the neck.

    Next, draw two ovals horizontally below the neck to make the shoulders. Our shoulders are about 2 head lengths wide.

    Now for the legs. Starting directly below the trunk, draw two more vertical ovals to create hips. From our waist to our knees we are about 3 heads tall. And from our knees to our feet we are about 2 heads tall.

    Now just add in straight lines for the arms, hands, legs and feet, and your person will really take shape!

    Kids can try making one that looks just look them; or have them draw one for Uncle Norm, Alanna, and Kevin and they can have their own drawing of the entire Prime Radicals gang!

    This activity will reinforce the use of indirect measurements as a tool for establishing reasonable estimates for body part dimensions, and the utility of widely used non-standard measures.
