For the next several weeks, weâ€™ll be looking at various aspects of teaching fractions: basic meanings, fraction models, finding equivalent fractions, comparing fractions, benchmarks and estimation.As an upper elementary or middle school math teacher, you may find yourself needing to review some of these fraction concepts before you can move on to the fraction curriculum for your grade level.

When this is the case (needing to review fraction concepts that aren’t part of your curriculum), there usually isn’t much time to squeeze in extra instruction…it can be tough!

We realize that some of our middle school kids just don’t ‘get’ fractions, but our time is limited. I’ve got a couple ideas at the end of the post for how to weave in some of the ‘fraction basics’ in middle school.But first, for this week, weâ€™ll start with some of the foundational fraction vocabulary terms.Â

**Teaching Fractions: Fraction Terms**

We might think so, but sometimes students have misunderstandings around these terms. When I looked for definitions of these terms, I found the following:

**Fraction:**“a number, written in the form a/b” and “a part of a whole, less than one”**N****umerator:**Â “theÂ top number in a fraction that tells how many parts are being considered” or “the number above the line in a common fraction, showing how many of the parts indicated by the denominator are taken”**Denominator:**Â “the bottom number that tells how many equal parts in a whole,”Â “the number below the line in a common fraction,” andÂ “a divisor”

When students learn about fractions in the earlier grades, fractions are represented with images like those below, withÂ the numerator being the colored part (or white part) and the denominator being the total number of pieces.

- Using the number line and the definition of “a number written in the form a/b” helps reinforce the idea that a fraction is a number that represents an amount, just as the number 2 represents two whole things.

*bigÂ*focus.

- When students understand that both fractions and decimals can be represented in the same way on the number line, it helps their understanding of the equivalence of decimals and fractions (and later percents). Fractions, decimals, and percents all represent parts of a whole…they’re just written differently.

â€‹We’ll look at fraction models more in depth in a future post.

**Equivalent fractions:**

- Fractions that have the
*same value*, or represent the same amounts. - This can be modeled as 2 shapes of the same size, cut into different numbers of pieces.
- This can be modeled asÂ two fractions marked by the same place on a number line (or ruler)Â that show the same number.

**Improper fractions:Â **fractions that represent an amount greater than 1, so the numerator is larger than the denominator (I know improper fractions are now often referred to as ‘fractions greater than one’ but I think it’s important for students to know and understand this term…..it’s still used in standardized tests at different levels

**Mixed numbers:** also represent amounts greater than 1, and are the combination of a whole number and a proper fraction

**Unit fractions:**Â fractions with a numerator of one

2) Keep visual representations around the room. For years, I kept a fraction/decimal/percentÂ number line up above my whiteboard. This kept some of the common fractions and their decimal/percent equivalences visible at all times for quick reference. Students definitely used this.

â€‹Visuals of fraction sets, number lines, and partitioned shapes are all helpful.

- Quick example:Â you can do a Number Talk where you ask students to consider whether 3/8 is more or less than Â½.

What other suggestions do you have to help middle school math students with the fraction basics?
