Draw the models and write the example below on the board.

Ask: How many base-ten rods can be drawn in the box to get the modeled total?

Direct students to start with the total after the equal sign. Next, have students complete the number sentence for

the models as shown below:

10 + _______ (50) + 2 = 62

Lead students to count the rods that they draw by 10 until they reach 50, then have them add the ten outside the
