About the Mathematics in This Unit
The second unit in mathematics called Counting Quantities, Comparing Lengths. The focus of this unit is on counting and comparing quantities and beginning to explore measurement by directly comparing objects to see which is longer.
Throughout this unit, students will be working toward these goals:

Counting A major focus of this unit is
counting. You can help your child learn to
count fluently by finding many opportunities to ask your child to count in different ways.
For example, sometimes count aloud together and see how high you can count. At other times, ask your child to count a small set of objects (“How many books are on the table?”) or the number of pictures on a page. A slightly different kind of question is “Can you make a group of 6 blocks?” or “Can you count out 7 pennies?” You can also ask your child to count to solve a problem; for example, “If everyone
needs a fork, how many forks do we need to set the table?”
Grab and Count Gather a set of objects, such as toy cars, blocks, or foam peanuts. Ask your child to grab a handful and count how many he or she grabbed. Then, ask your child to predict whether you will be able to grab more or less. Try it and find out. Your child can also grab two handfuls and see which holds more, the left
hand or the right.
Which Is Longer? Another major focus of this unit
is comparing objects to see which is longer. Find
opportunities to ask your child about the length of
different objects; for example, “What do you think
the longest part of this cereal box is? Do you think the cereal box is longer than the milk carton? How could we find out?”
Playing Compare We have been playing a card game
called Compare that is similar to the familiar card
game, War. You could play at home with a deck of
playing cards. Each player gets half of a deck of cards and puts them in a pile facedown. Both players turn over their top card, and the person with the greater number says, “Me.” Ask your child to explain how he or she knows which number is greater. The game is over when all of the cards have been turned over.
