[FREE] End of Year Math Assessments (Grade 4 and Grade 5)

The assessments cover a range of topics to assess your students' math progress and help prepare them for state assessments.

In order to access this I need to be confident with:

Adding decimals Subtracting decimals Multiplying decimals Dividing decimalsHere you will learn strategies on how to convert decimals to fractions.

Students will first learn about converting decimals to fractions in 4th grade math as part of their work in number and operations with fractions.

Converting **decimals to fractions **is when you represent a decimal as a fraction without changing its value.

Here is a visual model representing 0.43. The hundredths grid is made up of 100 equal parts. 43 pieces are shaded out of 100 equal parts which is \cfrac{43}{100}.

You can also use a place value chart to convert decimals to fractions.

How does this apply to 4th grade math and 5th grade math?

**Grade 4 – Number and Operations – Fractions (4.NF.C.5)**Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express \frac{3}{10} as \frac{30}{100}, and add \frac{3}{10} + \frac{4}{100} = \frac{34}{100}.

**Grade 5 – Number and Operations in Base 10 (5.NBT.A.3)**

Read, write, and compare decimals to thousandths.

In order to write a decimal as a fraction with a hundredths chart model:

**Represent the decimal on the hundredths chart.****The shaded part is the numerator, and the total amount of equal parts is the denominator.****Write the fraction and simplify if possible.**

In order to write a decimal as a fraction:

**Write the decimal in words.****The numerator is the digits of the decimal, and the denominator is the column of the last digit on the place value chart.****Write the fraction and simplify if possible.**

In order to write a decimal bigger than 1 as a mixed number:

**Write the decimal in words.****Keep the whole number.****The numerator is the digits to the right of the decimal point, and the denominator is the column of the last digit in the place value chart.****Write the mixed number and simplify if possible.**

0.22 → \cfrac{22}{100}

\cfrac{22}{100} \, can be simplified. The common factor between 22 and 100 is 2.

\cfrac{22}{100}=\cfrac{22\div2}{100\div 2}=\cfrac{11}{50}

\cfrac{22}{100} \, in lowest terms is \cfrac{11}{50}.

Convert 0.387 to a fraction.

**Write the decimal in words.**

0.387 in words is three hundred eighty-seven hundredths.

\cfrac{387}{1000} \, is in lowest terms.

Convert 1.7 to a mixed number.

**Write the decimal in words.**

1.7 in words is one and seven tenths.

**Keep the whole number.**

The whole number will stay at 1.

**The numerator is the digits to the right of the decimal point, and the denominator is the column of the last digit in the place value chart.**

1 is in the ones column, and 7 is in the tenths column.

7 will be the numerator and 10 will be the denominator of the fraction part of the mixed fraction.

Convert 2.04 to a fraction.

**Write the decimal in words.**

2.04 in words is two and four hundredths.

**Keep the whole number.**

2 will be the whole number.

2 is in the ones column, 0 is in the tenths column, and 4 is in the hundredths column.

4 will be the numerator and 100 will be the denominator of the fraction part of the mixed fraction.

**Write the mixed number and simplify if possible.**

2.04 as mixed number is \, 2\cfrac{4}{100}.

2\cfrac{4}{100} \, can be simplified because 4 is the common factor between 4 and 100.

\cfrac{4 \, \div \, 4}{100 \, \div 4}=\cfrac{1}{25}

2\cfrac{4}{100} \, in lowest terms is 2\cfrac{1}{25}.

- Use a visual model to introduce the topic since students should be familiar with how to create a fraction from a model.

- Use a number line to help students formulate number sense with decimal and fraction numbers.

- Reinforcing the decimal value will help students be able to write it in fraction form.

- When teaching the math lessons on converting fractions to decimals, have students change improper fractions to mixed numbers first before making the conversion.

**Placing the decimal number in the wrong columns on a place value chart**

For example, placing the 3 in the decimal number 0.03 in the tenths column instead of the hundredths column.

**Forgetting to write the fraction in lowest terms**

Always look to see if there is a common factor between the numerator and the denominator of the fraction.

**Confusing the numerator and the denominator**

The numerator is the top number, and the denominator is the bottom number.

When converting a decimal to a fraction, the digits of the decimal will be the numerator (top number) and a power of ten will be the denominator (bottom number).

Yes, when converting a decimal to a fraction the denominator of the fraction will always be a power of ten. This is because our decimal system breaks apart the decimal number into tenths (\cfrac{1}{10}), hundredths (\cfrac{1}{100}), thousandths (\cfrac{1}{1000}), etc.

It’s a good practice to always write a fraction in lowest terms, but refer to your state standards for specific guidance.

Yes, you can go from decimal representation to fraction representation and vice versa. For example, to convert \cfrac{9}{10} \, to a decimal, you can put it on the place value chart.

9 will go in the tenths column, so the decimal representation of \cfrac{9}{10} \, is 0.9.

No, there are other ways to convert decimals to fractions. You can use the fraction calculator converter.

A decimal fraction is when the denominator of the fraction is a power of 10. For example, \cfrac{3}{100} \, is a decimal fraction because 100 is 10^2.

Yes, repeating decimals are rational numbers. Rational numbers can be written as fractions. So, repeating decimals can be written as fractions. You will learn how to do this fraction conversion in 8th grade math.
