Times as Many: Multiplication as Comparison
Aligned to 4.OA.A.1 — Common Core State Standards for Mathematics.
What this lesson teaches
A multiplication equation can tell you how many times bigger one amount is than another. Saying 35 = 5 x 7 means 35 is 5 times as many as 7, or 7 times as many as 5.
Worked example
Sara has 4 stickers. Ben has 3 times as many. 'Times as many' means multiply: 3 x 4 = 12. So the equation 12 = 3 x 4 shows Ben has 12 stickers, which is 3 times as many as Sara's 4.
Practice questions
- Write an equation to show that 24 is 4 times as many as 6.
- A dog is 2 years old. Its owner is 6 times as old. Write the equation and find the owner's age.
- There are 40 red beads and 8 blue beads. Write a multiplication equation comparing them, then say it in words.

Veces mas: la multiplicacion como comparacion
Una ecuacion de multiplicacion puede decir cuantas veces mas grande es una cantidad que otra. Decir 35 = 5 x 7 significa que 35 es 5 veces la cantidad de 7, o 7 veces la cantidad de 5.
Ejemplo: Sara tiene 4 calcomanias. Ben tiene 3 veces esa cantidad. 'Veces mas' significa multiplicar: 3 x 4 = 12. Entonces la ecuacion 12 = 3 x 4 muestra que Ben tiene 12 calcomanias, que es 3 veces las 4 de Sara.
