OVERVIEW & PURPOSE
Week 1 of the 2nd Grade CountFast program focuses on a review of the recognition of the numbers 0 – 12, as well as the addition, subtraction, and equal signs often used in simple equations using those numbers. This module includes lessons to practice reading and writing numbers and organizing them based on their values. Spend 15 minutes each day on one of the activities listed in this module. Card decks should go home with students each day for additional practice with a parent at home. Each week, a new deck is introduced and the previous deck is for the student to keep at home for continued practice.
EDUCATION STANDARDS
1. CCSS.MATH.CONTENT.K.CC.A.3 Counting and Cardinality
2. NCTM Standard: connect number words and numerals to the quantities they represent
3. NCTM Standard: develop understanding of the relative position and magnitude of whole numbers
OBJECTIVES
1. Read and write the numbers zero through twelve in digit and word form.
2. Develop fluency with mental addition and subtraction calculations using the numbers 0-12.
Review of 1st Grade Pack – Day 1
Teacher Model/Direct: Use the yellow cards from the deck. These have the numbers 0-12 written as digits and as words. You will also find a card for addition (plus), subtraction (minus), and equal. Hold up the yellow cards one at a time and ask students to say what the number or symbol is. Discuss the meaning of each. See how quickly the students can say or represent the numbers as the teacher quickly holds up one card after another. Review the proper way to write each of the numbers.
Student Activity: Give each student a deck and ask them to take out the yellow cards. Have students lay out the numbers 0-12 in order in front of them. Touching each card one at a time, say the numbers in order from least to greatest. Repeat procedure but say the numbers in order from greatest to least. Students should also practice properly tracing the numbers using the dotted lines on each card, while saying that number aloud.
Home Activity: Students will take home the deck and the “CountFast Home Connection” letter. Students will review the yellow cards with parent(s). Parents can record on the “Reading Time Record” card how many seconds it takes the child to correctly identify (read) each of the cards, and how long it takes to trace each of the numbers. Parents also work with child to put the numbers in order from least to greatest, and from greatest to least.
Review of 1st Grade Pack – Day 2
Teacher Model/Direct: Review recognition of the numbers 0-12, and the symbols for addition, subtraction, and equal by using the yellow flash cards. Model/Review for students the proper way to write each of the digits and symbols. Ask guiding questions about “how many more” or “how many fewer”, thinking of the numbers on a number line. (For example: How many more is 7 than 4? Students can lay the yellow number cards out in front of them in order and find the four. Then touch-count each card after the four up to the seven. They will touch three cards, 5, 6, and 7, to determine that 7 is three more than 4.)
Student Activity: Ask students to observe their BLUE cards and notice that there are two sets of the numbers 0-6, as well as an addition and an equal sign. Working in partners, ask students to build accurate addition equations with their blue cards (Ex: 2 + 3 = 5). Talk about how to prove that the equation is correct. Remind students of the Property of Addition and how that property can be used to make counting up easier. (Ex: it might be easier for the student to do 3 + 2 instead of 2 + 3). Practice building and solving equations using the numbers 0-6.
Home Activity: Students will practice with the yellow cards by putting the numbers in order and solving “how many more” and “how many fewer” questions. Parents will use the “Reading/Writing Time Record” to record how many seconds it takes the child to identify/trace all of the yellow cards correctly. Using the blue cards, students will demonstrate to parents how to make accurate addition equations.
Review of 1st Grade Pack – Day 3
Teacher Model/Direct: Use the yellow cards to review putting numbers in order. Ask students “how many more” and “how many fewer” questions, and have students touch-count using the cards. Model how to make an equation/number sentence using the cards. (Ex: 2 + 3 = 5)
Student Activity: With a partner, practice building correct addition number sentences (equations) using the BLUE cards in the deck. Write each correct equation on paper. Let another group check the problems for accuracy.
Home Activity: Students will practice putting the yellow cards in numerical order and demonstrate building number sentences for parents using the blue cards. The goal is to create seven correct equations. Parents will use the “Addition Time Record” card to keep track of how long it takes the child to create 7 accurate equations each day. Each day, the child should improve in speed and accuracy.
Review of 1st Grade Pack – Day 4
Teacher Model/Direct: Introduce the PINK cards in the deck. Review the concept of subtraction as a smaller amount being taken away from a larger amount. The pink cards have the minuends (larger #’s) of 7-12, as well as the numbers 0-6 which can be taken away from those minuends. Play the subtraction equation game. Call out subtraction equations (ex: 11 – 4 =) for students to build using the pink cards. Check to see that students are able to put the correct answer (7). Discuss whether or not Commutative Property can be applied to subtraction. (Can we do 4 – 11? Why not?)
Student Activity: Have students work with a partner. Using one set of PINK cards, partners should take turns building accurate subtraction equations of their choice (or the partner can call out an equation to solve). Partners should check each other’s accuracy and have a strategy for proving results. Play until each partner has completed 7 different equations. You can also have students write their equations on paper and let another group/partnership check for accuracy.
Home Activity: Students will play the subtraction equation game with parents and use the ‘Subtraction Time Record’ card to keep track of how long it takes to create 7 accurate equations.
Review of 1st Grade Pack – Day 5
Teacher Model/Direct: Review each of the activities from this week. Discuss with students how they are improving on their time record cards as they read/write/order numbers with parents at home. Discuss the addition and subtraction equations that students have been able to make and solve this week.
Student Activity: With a partner, practice building correct addition and subtraction number sentences using the BLUE and PINK cards in the deck. Using their own decks, students can race their partners to see who can create 7 accurate addition and subtraction equations the fastest.
Home Activity: Students will practice creating and solving subtraction equations using the PINK cards from the deck, as well as review addition equations using the BLUE cards
