As we were “sharing” our food I would consistently reinforce the concept that the denominator tells us how many equal groups there are to make a whole. And the importance that their groups were equal.

We hope you and your students have fun exploring the world of fractions with these simple, food-themed activities!

Oecologia 136(2): 261–9.All things in math must absolutely be connected to the real world for students right from the start. Thank you, thank you, THANK you, Jen, for sharing your math expertise–and totally cool idea!– with us! Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified form (the provided calculator computes the simplification automatically). Below is an example using this method. a

In a business-as-usual scenario, the authors expect the world to emit around 1356 billion tonnes of CO 2-we by 2100.

International Journal of Osteoarchaeology 13(1–2): 54–65. An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers.

Statistics and Computing 10(4): 325–337.When cutting a sandwich, show your child how you can cut a whole sandwich into two equal parts, and explain that we call each part a half. Point out that we could put the two halves together again to make the whole. Try halving in different ways, such as cutting a whole sandwich into two equal rectangles or triangles. Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification. a Morrison DJ, Dodson B, Slater C, Preston T (2000) 13C natural abundance in the British diet: implications for 13C breath tests. Rapid Communications in Mass Spectrometry 14(15): 1321–1324. I love these because it shows that sometimes a whole isn’t just one piece of food. A whole can be the total amount of any equal thing. Imagine making a fruit salad with strawberries, oranges, and bananas. Use 2 strawberries, 3 oranges, and 4 bananas. You can express the fractions as 2/9, 3/9, and 4/9, respectively, representing the fraction of each fruit in the salad. · Time for Math
