We can see that
1/1 = 2/2 = 4/4 = 8/8
They are equivalent fractions
We can see that 2/8 is the same length as 1/4
So 2/8 = 1/4
They are equivalent fractions

Look at the equivalent fractions – each time the numerators double, the denominators also double.
Which other fraction will be equivalent?

Think of a pizza cut into six pieces
How many sixths are equivalent to ½?
Now we’ve learnt what equivalent fractions are – let’s find some ourselves.
Good Luck!
Activity: “Math About Me Poster”Think about how math is part of your personal life. Gather this Information on a separate sheet of paper. Today you will be making a “Math about me Poster” that illustrates That information about yourself. You will draw a picture and/or write a math problem that represents that information. Here are a few questions to think When thinking about math in your life:•Fractions or whole numbers in your birthday•Address numbers•Phone numbers •Sports numbers•Favorite/lucky numbers•Number of pets •Number of people in your family\•Number of cars your family drivesCan you think of any other ways in which math is part of your life?
1) Glue a picture of yourself into the middle.2) Write your name in one of the 8 rectangles.3)Then, set out the important numbers in your life! Write
math problems4) Lastly, you will illustrate (draw) and decorate the
poster to make it look awesome!!! Use construction paper, magazines, pictures, etc.
Have fun!!!
