there are 14 bikes for sale at a bicycle store. four of the bikes are black, 5 are white, and the rest are red. how many bikes are red?

a.

translate into an equation. 4 + 5 + r = 14

b.
use logical reasoning. there were 14 bikes to start with. subtract the number of black bikes (4) and subtract the number of white bikes (5). the remaining bikes must be red.

c.
work backward. start with 14 bikes and add 4. then subtract 5. the number left is the number of red bikes.

d.
draw a diagram. draw 14 circles. cross out 4 of the circles and then cross out 5 more circles. color the remaining circles red.

billy put up some balloons for a party. he had 4 times as many green balloons as red ones. there were 3 red balloons. during a game, 2 green balloons popped. then another 5 green balloons popped. how many green balloons did billy have left?

a.

use objects to model the problem. use toothpicks to represent the green balloons. count out a total of 4 groups of 3 toothpicks. remove 2 toothpicks and then 5 more. count the remaining toothpicks to find the number of green balloons left.

b.
work backwards. start by adding the number of green balloons that popped (5 + 2) then multiply the sum by 4. subtract the number of red balloons (3) and that gives the number of green balloons that were left.

c.
use logical reasoning. step 1. multiply 3 × 4 to figure out the total number of green balloons. step 2. add 2 + 5 to figure out how many green balloons popped. step 3. subtract the sum in step 2 from the product in step 1 to find out the number of green balloons that were left.

d.

translate into an equation. (3 × 4) – (2 + 5) = g

comic books cost $1, paperback books cost $3, and hardcover books cost $5 at the used book store. sara bought 2 comic books, 5 paperbacks, and 2 hardcover books. how much money did sara spend?

a.

use objects to model the problem. use coins to represent $1. drop 1 coin into a jar 2 times for the cost of comic books. drop 3 coins into the jar 5 times for the cost of the paperbacks. drop 5 coins into the jar 2 times for the cost of the hard cover books. count the coins in the jar.

b.

draw a diagram. draw 2 squares and write $1 inside each. draw 5 circles and write $3 inside each. draw 2 triangles and write $5 inside each. add all the dollar amounts inside the shapes to find the total sara spent.

c.

use logical reasoning. sara bought 2 comic books at $1 each for a total of $2. she bought 5 paperbacks at $3 each for a total of $15. she bought 2 hard cover books at $5 each for a total of $10. so sara adds $2 + $15 + $10 to find the total amount she spent.

d.

translate into an equation. (1 + 3 + 5) × (2 + 5 + 2) = n
