Are these fractions equivalent to 1/4?

Rating
0.0 stars

I use this help students make sense of equivalent fractions and deepen their understanding.  It gives students an opportunity to work with fractions that are equivlanet to 1/4, but also identify fractions that are not equivalent to 1/4.  This activity will reinforce the concept that when making equivalent fractions the numerator and denominator need to be multiplied by the same number.  It's like multiplying by a whole or one, that's why the fractions are equivalent.

Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed! The students will be given mutiplication and division problems which they must answer. They also have the option of being given a number then stating the factors of how that number was attained using either multiplication or division.

Bounded Fraction Finder
Unrestricted Use

Rating
0.0 stars

Determine the value of two fractions you have chosen (which are represented as points on a number line). Then find a fraction whose value is between your two fractions and determine its value. This manipulative is the same as "Bounded Fraction Pointer" but there is no arrow to help the user determine the value of a fraction between the two endpoints. Bounded Fraction Finder is one of the Interactivate assessment explorers.

Comparing Fractions with a Different Whole
Conditional Remix & Share Permitted

Rating
0.0 stars

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.
