Blog 5 Equivalent Fractions

 

Despite the fact that we are continuing to study about fractions and moving on to our next topic, equivalent fractions, I am feeling apprehensive and a little out of my element. Several videos had to be seen in order for me to be confident in my comprehension of comparable fractions before I could introduce them.

To begin the lesson, I introduced vocabulary words with student friendly definitions, then I explained that equivalent fractions are fractions that do not look alike, but have the same value. Then, we watched two videos on how to find equivalent fractions. Next, I explained and modeled on the board to find equivalent fractions, by multiplying the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3. We did some group work on liveworksheets.com and independent work. 

2 times 3 over 7 times 3 equals 6 over 21

    Another great way to teach equivalent fractions is to use a visual. a great way to do this is by using fractions strips or bar models. I love using both but always make my students use a bar model when comparing fractions to see if they are equivalent or not.
