Chapter Menu**I will model and create multiplication stories.**Lesson 1—Get Ready 1**multiplication**Lesson 1—Get Ready 2**Use counters to model this multiplication story:**• I have 3 different flavors of ice cream. There are 5 scoops of each flavor. How many scoops of ice cream are there in all? Lesson 1—Teach**There are 3 flavors, so there are 3 groups.**There are 5 scoops in each group. Lesson 1—Teach**How many scoops are there in all?**15 scoops Lesson 1—Teach**There are 3 bird feeders. 2 birds are on each bird feeder.**How many birds are there in all? 6 birds Lesson 1—Check**I will model skip counting to find the total in equal**groups. Lesson 2—Get Ready 1**equal groups**Lesson 2—Get Ready 2**1**2 3 4 5 6 7 8 9 10 How many equal groups of 2 counters can you make? 10 equal groups Lesson 2—Teach**2**4 6 8 10 12 14 16 18 20 • Find the total number of counters by skip counting by twos. 20 total counters Lesson 2—Teach**1**2 3 4 5 • How many equal groups of 4 counters can you make? 5 equal groups Lesson 2—Teach**12**16 20 4 8 • Find the total number of counters by skip counting by fours. 20 total counters Lesson 2—Teach**How many equal groups of 3 are there?**4 groups of 3 Lesson 2—Check**Skip count. Write how many hearts in all.**12 hearts Lesson 2—Check**How many equal groups of 2 are there?**5 groups of 2 Lesson 2—Check**Skip count. Write how many suns in all.**10 suns Lesson 2—Check**I will draw a picture to solve a problem.**Lesson 3—Get Ready 1**What do I know?**Underline what you know. Lesson 3—Teach**What do I need to find?**Circle the question. Lesson 3—Teach**How will I solve the problem?**I will draw a picture. Lesson 3—Teach**Draw a picture.**5 wreaths 4 8 4 pinecones per wreath Brenda needs 20 pinecones in all. 12 16 20 Lesson 3—Teach**Look back.Is my answer reasonable?**yes Lesson 3—Teach**Draw a picture to solve.**• Teagan bought 4 bags of apples. Each bag had 4 apples in it. How many apples did Teagan buy in all? 16 apples Lesson 3—Check**I will add and multiply equal groups.**Lesson 4—Get Ready 1**multiplication sentence**• product Lesson 4—Get Ready 2**How many equal groups of boxes are shown?**2 equal groups Lesson 4—Teach**How many boxes are in each group?**5 boxes Lesson 4—Teach**What repeated addition problem can we make from the picture?**5 + 5 = 10 Lesson 4—Teach**How would you write this repeated addition problem as a**multiplication sentence? 2 × 5 = 10 Lesson 4—Teach**How many equal groups of boxes are shown?**3 equal groups Lesson 4—Teach**Write the repeated addition problem to show the picture.**4 + 4 + 4 = 12 Lesson 4—Teach**Write the multiplication sentence to show the picture.**3 × 4 = 12 Lesson 4—Teach**The first number tells how many groups there are.**3 × 4 = 12 Lesson 4—Teach
