Learning Intention: Students will identify that a unit fraction is one part of a whole; indicate that the more parts a whole is divided into, the smaller the parts will be.
Success Criteria: Students will be successful when they can independently explain numerator, explain denominator, compare fractions using models, and decompose a fraction into a sum of unit fractions with the same denominator.
Essential Questions: - How can I represent these fractions? - What is the relationship between the two fractions?
Standards Covered
EE.6.NS.1. Compare the relationships between two unit fractions. EE.7.NS.1. Add fractions with like denominators (halves, thirds, fourths, and tenths) with sums less than or equal to one.
EE.8.NS.1. Subtract fractions with like denominators (halves, thirds, fourths, and tenths) with minuends less than or equal to one.
Fractions are important because they tell you what portion of a whole you need, have, or want.
Fractions are used in baking to tell how much of an ingredient to use.
Fractions are used in telling time; each minute is a fraction of the hour.
Money is another place fractions are used. For example, a quarter is one fourth of a dollar (1/4). A dime is one-tenth, represented by 1/10. We could continue by talking about pennies and nickels.
Subtracting Fractions With Like Denominator Student Work
Learning Intention: Students will add and subtract fractions with common denominators.
Success Criteria: Students will be successful when they can independently add or subtract fractions with denominators of 10 and 100.
Essential Questions: - What is the difference of two fractions? - Which part of the fractions do I add? - Why do I not add the denominators?

Strategy
To subtract fractions there are Two Simple Steps:
Step 1: Make sure the bottom numbers (the denominators) are the same.
Step 2: Subtract the top numbers (the numerators), put that answer over the denominator.
