🍕 Adding Fractions with the Same Denominator

What you’ll learn

1. Fractions Are Equal PartsUnderstand a fraction as equal parts of a whole, and read the top and bottom numbers.A fraction shows equal parts of a whole. The bottom number (denominator) tells how many equal parts the whole is split into, and the top number (numerator) tells how many parts you have. The pieces must all be the same size.
2. Add the Tops, Keep the BottomAdd fractions with the same denominator by adding the numerators and keeping the denominator.When fractions have the same bottom number, the pieces are the same size, so you just count how many you have in total. Add the top numbers and keep the bottom the same: 1/5 + 2/5 = 3/5.
3. Your Turn to AddPractice adding same-denominator fractions, including sums that make one whole.Adding same-denominator fractions works everywhere, from measuring jugs to matching games. Sometimes the parts add up to the whole: 2/4 + 2/4 = 4/4 = one whole. Always add the tops and keep the bottom.
