We will continue Chapter 10, measurement while reviewing 2-digit addition. 

In this chapter, your student is learning to compare and measure the lengths of objects. The lessons address ordering objects by length, comparing the lengths of two objects using a third object, using like objects to measure length, and solving word problems that compare lengths.

The vocabulary words for this chapter are shortest, longest, length, measure, length unit, and inch.

There are many situations where you can practice measuring and comparing lengths. Look for opportunities to reinforce these skills while playing with your student! As you and your student spend time together, use his or her toys, games, and art supplies to practice math skills. Use the following strategies to involve your student: • When playing a game, have your student compare the lengths of the objects involved. For example, ask, “Is the game card or the spinner longer? Is the board longer or shorter than the game money?” • When drawing or coloring, select three objects, such as three crayons, or a marker, a paintbrush, and a colored pencil. Ask your student to order the items from longest to shortest or shortest to longest. Ask your student to explain how he or she determined how to order the objects. • While playing with toys, choose three items. Compare two of the items to a third, then have your student compare the first two. For example, say, “The toy drum is shorter than the flute. The xylophone is longer than the flute. Is the toy drum longer or shorter than the xylophone?” • Use a small item, such as a toy car, number cube, or playing card, to measure the length of other toys. First, have your student estimate the length of the toy in terms of the smaller item. Then, have him or her measure to find the length. For example, ask, “About how many cards long do you think the teddy bear is?” Then, line up cards side by side beside the bear without gaps or overlaps. Count to find how many cards in length the bear is. By the end of this chapter, your student should feel confident with the learning targets and success criteria on the next page. Encourage your student to look for other opportunities to compare and measure lengths, such as measuring clothing items, snack items, or plant leaves. Have a great time practicing measurement!
