1. 1.

   Pia had some buttons and found 6 more: 14 in all. Let b be the buttons at first. The bar for 14 is cut into b and 6. Which equation matches the story?

   • 6b = 14
   • b − 6 = 14
   • b + 6 = 14
   • b + 14 = 6
2. 2.

   Tala rode 19 laps. Luz rode 3 more than Tala. Let n be Luz's laps. The bars show Tala's 19, a longer bar for Luz, and a gap of 3. Which equation matches the story?

   • 3n = 19
   • n = 19 − 3
   • n = 19 + 3
   • n/3 = 19
3. 3.

   Luz read 14 pages, 3 fewer than Noah. Let a be Noah's pages. The bars show Luz's 14, a longer bar for Noah, and a gap of 3. Which equation matches the story?

   • a = 14 − 3
   • a − 3 = 14
   • 3a = 14
   • 3 − a = 14
4. 4.

   Bo has 15 buttons. Pia has 4 fewer than Bo. Let t be Pia's buttons. The bars show Bo's 15, a shorter bar for Pia, and a gap of 4. Which equation matches the story?

   • t = 15 + 4
   • 4t = 15
   • t/4 = 15
   • t = 15 − 4
5. 5.

   After 9 beads leave Zee's jar, 11 are left. Let j be the beads at first. The bar for j has 9 cut off and 11 left. Which equation matches the story?

   • j + 9 = 11
   • j − 9 = 11
   • 9 − j = 11
   • 9j = 11
6. 6.

   Luz has 21 buttons, 3 times as many as Ari. Let b be Ari's buttons. The bar for Luz's 21 is made of 3 equal bars of b. Which equation matches the story?

   • b = 3 × 21
   • b − 3 = 21
   • 3b = 21
   • b + 3 = 21
7. 7.

   Tala has 20 stickers, 4 times as many as Bo. Let m be Bo's stickers. The bar for Tala's 20 is made of 4 equal bars of m. Which equation matches the story?

   • m − 4 = 20
   • 4m = 20
   • m = 4 × 20
   • m + 4 = 20
8. 8.

   Noah has 5 acorns. Esme has 3 times as many as Noah. Let a be Esme's acorns. The bar for Esme is made of 3 equal bars, each Noah's 5. Which equation matches the story?

   • a = 3 × 5
   • a + 3 = 5
   • a = 5 + 3
   • a = 5/3
9. 9.

   Pia has 3 crayons. Jun has 4 times as many as Pia. Let z be Jun's crayons. The bar for Jun is made of 4 equal bars, each Pia's 3. Which equation matches the story?

   • z + 4 = 3
   • z = 3/4
   • z = 4 × 3
   • z = 3 + 4
