Sarah has 452 beads. She gives 128 beads to her friend. Represent this situation with a number line to show how many beads Sarah has left.

Start at 452 on the number line and move 128 spaces to the left. The number you land on is the number of beads Sarah has left.

Michael has 275 baseball cards. John has 130 fewer cards than Michael. Draw a picture to represent how many cards John has.

Draw a bar representing Michael's cards (275). Then draw a smaller bar representing John's cards, showing that it is 130 less than Michael's.

Step 1: 425 - 150 = ? (books sold on Tuesday). Step 2: 425 + (425 - 150) + 230 = ? or 425 + Tuesday + 230 = ? (total books sold)
