3nf1
Look at a picture model and write the fraction it shows. Identify the numerator and denominator in a fraction. Match a shaded part of a whole to the correct fraction notation.
3nf1
Match a written fraction to a picture that shows the same amount shaded. Tell how many equal parts the whole is split into and how many parts are shaded. Notice when pictures show different-sized parts and choose only models with equal parts.
1g3
Match a written fraction name (like “three fourths”) to the correct fraction. Use the denominator to tell how many equal parts the whole is split into. Use the numerator to tell how many parts are being counted.
3nf2a
Find where a fraction belongs between 0 and 1 on a number line. Use the denominator to see how many equal parts the whole is split into on the number line. Use the numerator to count how many parts to move from 0 to reach the fraction. Use benchmarks like 0, 1/2, and 1 to decide if a fraction is closer to the start, middle, or end.
4nf3a
Add two fractions by combining their parts to make a total amount. Use pictures or fraction models to see what each fraction means before adding.
3g2
Decide whether a shape has been split into equal-size parts. Tell the difference between equal partitions and uneven partitions in pictures. Connect a partitioned shape to the idea of a fraction as equal parts of one whole. Explain why a partition is not correct when the pieces are different sizes.
2g3
Read a fraction and say its name using the right word for the denominator (like halves, thirds, or fourths). Match a written fraction name to the correct fraction. Use the denominator to tell how many equal parts the whole is split into. Use the numerator to tell how many parts are being counted.
3nf2b
Find where a fraction belongs on a number line between 0 and 1. Use the denominator to see how many equal parts the whole is split into on the number line. Use the numerator to count how many parts from 0 to reach the fraction’s point. Recognize benchmark points like 0, 1/2, and 1 to help place and compare fractions.
3nf1
Write the shaded part of a picture as a fraction using a numerator and denominator. Count equal parts in a shape to figure out the denominator. Count shaded parts to figure out the numerator. Match a visual fraction model to the correct numeric fraction notation.
3nf1
Explain a fraction as “part of a whole set,” using the numerator as the count shown and the denominator as the total.
3g2
Split a shape into equal-size parts and explain that each part is the same area. Spot when parts are not equal and know that they do not make fair fractions.
3nf1
Match a shaded picture or model to the fraction it shows. Count equal parts to figure out the denominator and count shaded parts to figure out the numerator. Recognize the same fraction shown with different shapes or layouts (like bars, circles, or grids).
Read a fraction and say it using the correct words. Write a fraction in word form using the right spelling for the denominator (like thirds, fourths, fifths). Match the numerator to the correct counting word (one, two, three, etc.) when writing fractions. Use singular and plural fraction words correctly (like one half vs. two thirds).
3nf1
Shade a given number of equal parts on a fraction bar Count the equal parts in the whole to find the denominator Write the fraction that is shaded, such as 3/8 or 5/10 Understand that the numerator counts the shaded parts while the denominator counts every part
3nf1
Shade the correct number of parts on a bar to match a fraction Understand that the bottom number tells how many equal parts the whole is split into Understand that the top number tells how many parts to color Connect a written fraction to its picture
3nf1
Name the fraction of a whole that is left after some equal pieces are removed Count the missing pieces in a picture to name the fraction that was eaten Use the total number of equal pieces as the denominator Recognize the same fraction idea in round wholes and in rectangular wholes
Choose which fractions have a given number as the numerator Choose which fractions have a given number as the denominator Tell the difference between the numerator and the denominator of a fraction Notice that a question can have more than one correct answer
Read a fraction written with symbols. Write the numerator and denominator using correct fraction words. Use singular and plural fraction names correctly. Identify the numerator and denominator in a fraction.
Read a fraction written in words. Write the numerator and denominator in the correct positions. Use a fraction bar to write a fraction symbol. Connect fraction vocabulary to fraction symbols.
3nf1
Practice adding fractions that share the same denominator Understand how parts combine to make a whole Read word problems and figure out which fractions to add Recognize when combined parts equal one whole
