In the previous chapter, your student learned that two parts make a whole. In this chapter, your student uses an addition equation, called addition sentence, including a plus sign and an equal sign, to show two parts and a whole. 

Your student learns two different ways to apply addition. One way involves groups of people or animals actively joining. For example, 2 students may join 3 students to play a game so there are 5 students playing in all. Another way involves non-moving objects, such as counters, to focus on parts and a whole. 

Your student discovers patterns: When adding 0 to a number, the answer is the number. When adding 1 to a number, the answer is the next counting number. Finally, your student finds a missing partner number (addend) by adding or counting on to the given partner number. For example, for 5 + ? = 9, your student might use counters to figure out that 5 and 4 more equals 9. The goal of the chapter is to build an understanding of addition, not to memorize facts, so don’t worry if your student needs to count objects to find answers. Here are some activities you can use to practice with your student. 

• If you have two number cubes, change the sixes to zeros by covering the sixes with masking tape. Invite your student to toss the two cubes to make partner numbers. Encourage your student to name the partner numbers and the total, or the number in all. Expand the activity to include writing an addition sentence to show the parts and the whole. 
• Play “Get to Ten” using fingers to find missing partner numbers. One player holds up any number of fingers. The other player names the number of fingers and how many more fingers are needed to get to ten. For example, if a player holds up 7 fingers, the other player might say, “Seven fingers; it takes three more to get to ten.” 
• Make two sets of cards, numbered 1 through 5. Mix up the cards and spread them facedown on a table. Players take turns flipping over two cards to find partner numbers that make 6, for example, 2 and 4. If a player finds partners, the player gets to keep the cards. If not, the player turns the cards facedown. The player with the most cards wins! 

In this chapter, In this chapter, your student will put together two small groups of objects (parts) to form a larger group (the whole). They will also take apart a whole group to form two parts. They will use a number bond to show the numbers of objects in the parts and in the whole. 

Learning how two parts make a whole is the first step in learning to add and subtract. The vocabulary words for this chapter are put together, take apart, part, whole, partner numbers, and number bond. Use the activities below to help your student practice putting together parts to make a whole and taking apart a whole to make parts.

• Drop up to ten pennies on a table. Have your student name the number of heads, the number of tails, and the number of all pennies. 
• Make a line on a tabletop with chalk or tape. Invite your student to drop up to ten dried beans or other small objects on the table. Ask your student to write the numbers of beans that fell on each side of the line and the number of beans in all. 
• On the count of three, you and your student each show up to five fingers. Have your student name the number of fingers each person is showing and the number of fingers in all. 
• Set out up to ten buttons or other small objects. Place a cup on a table. Players take turns trying to toss all the buttons, one at a time, into the cup. After each round, guide your student to write the score as the number of buttons in the cup and the number of buttons outside the cup. Talk about how the two numbers are parts of the whole. 

In this chapter, your student compares numbers up to 10 as equal to, greater than, or less than each other. Your student also learns to classify objects into categories. You can use the activities below to practice and review number comparisons, sorting and classifying, and data collection. 

• Place up to ten pennies on a table. Ask your student to place an equal number of pennies on the table. After you have played for a while, vary the game so that your student sets out a number of pennies that is greater than or less than the number of pennies you place on the table.
• Help your student make a chart to tally and compare the number of cans of vegetables that are peas and the number of cans of vegetables that are not peas.

This week we will be comparing numbers up to 10 as greater than, less than, or equal to. Students will be learning how to classify objects into categories. They will be sorting, comparing, and classifying this week. Below are some ideas on how you can practice this at home. 

• Use scraps of paper to make two sets of number cards from 0 to 10. Mix up the cards and place them face down on a table. Each player takes a number card and turns it faceup. Players compare the numbers. The player who has the greater number takes the faceup cards. Play continues until there are no cards left in the pile. The player with more (or the most) number cards wins.
• Invite your student to help you sort the laundry. Have your student describe the sorting rule, such as light and dark items or clothing and towels. Have your student count the number of items in each group. 

In math, we will be finishing our 3rd chapter and continue to practice counting and writing the numbers 9-10. In addition to this, we will also work on ordering numbers when they are out of order. To support students with their learning, we will be using centers and crafts! 

This week in math, we will continue Chapter 3 and continue practicing writing and counting numbers 6-10. We will also practice these skills with playdough and other activities that include counting bears and number blocks! 

On Tuesday, we will finish up chapter 2, where we will compare numbers 0-5. On Wednesday, we will be having our chapter 2 test. On Thursday, we will take our chapter 3 pre-test, and on Friday, we will begin chapter 3, writing and counting numbers 6-10. 

We will begin chapter 2 in our math curriculum this week! In chapter 2, we explore quantities and determine if groups are greater than, less than, or equal to other groups. The following week, we will have our chapter 2 assessment. 

This week in math, we will continue to work on writing and counting numbers from 0 - 5. On Thursday, we will have our first math assessment! On Friday, we will compare numbers 0 - 5. 

This week in math, we will be counting and writing numbers zero through five! We will also practice these skills with playdough and other activities that include counting bears and number blocks!
