Unit 4, Lesson 12

Add tens to a two-digit number.

EngageNY 60 min(s)

In this lesson, students use linking cubes, dimes, and pennies to add multiples of 10 to two-digit numbers that include both tens and ones. They recognize that when tens are added to a number, the ones remain the same. They also represent their computations using number bonds, quick ten drawings, arrow notation, and the place-value chart.
