Fraction Grids

How do grids show me fractions and decimals?

Hundredths Grids

-- Grids like this show that your fraction will have denominator of 100.

-- Theses grids also tell you that your decimal will have hundredths in the name.

Here are examples of fractions and decimals that could be used to describe a hundredths grid

-- 0.05

-- 0.34

-- 0.7

-- 0.20

-- ⁴²/₁₀₀

-- ⁸/₁₀₀

_{-- zero and three-hundredths (o.o3)}

Multiple Choice

Which fraction would you not find on a hundredths grid?

• ⁹²/₁₀₀

• ³³/₁₀₀

• ⁵/₁₀₀

• ⁴²/10

How do you read shaded hundredths grids?

• Look to see how many squares are shaded

• To make a fraction you write that number over 100-- ³/₁₀₀

• To make that a decimal, you place the numbers in the right place values-- 0.03 -- three is in the hundredths

How can I change this grid into a fraction?

• Count that you have 62 total shaded

• Place 62 over 100

• ⁶²/₁₀₀

How can I change this grid into a decimal?

• Count that you have 62 total shaded

• You know that your decimal read aloud is "sixty-two hundredths"

• So you write it as 0.62

Multiple Choice

Which fraction would you not find on a tenths grid?

• ⁴/₁₀

• ⁹/₁

• ⁷⁸/₁₀

• ¹⁹/₁₀

How do you read a shaded tenths grid?

-- Look to see how many total are shaded

-- To make a fraction you put that number over 10-- ³/₁₀

_{-- To make a decimal, you place the numbers in the right place values-- 0.3-- three is in the tenths place. OR 0.30}
