### Lesson plan

# Skip Counting to Understand Multiplication

#### Learning Objectives

Students will be able to use skip counting as a strategy to multiply two single-digit factors.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

*(5 minutes)*

- Ask your students to join you as you count by two aloud. Count to 20.
- Tell students, "We just skip counted by two."
- Review: What is
**Skip counting**? (Counting by a number other than one.) Why do we do it? (To count numbers or items faster.) - Relate skip counting to multiplication (i.e., skip counting can help us understand multiplication because it helps us count in equal groups to reach a number, like counting ten groups of two to get to 20).

#### Explicit Instruction/Teacher modeling

*(10 minutes)*

- Draw a number line on the board and show students how they would make ‘jumps’ along the number line to skip count by twos.
- Point out the equal sized jumps and explain that when they are skip counting, they are actually counting equal sized groups.
- Display a hundreds chart inside plastic sleeve so that it is wipeable.
- Count by twos and, using a wipeable pen, circle each multiple of two up to 20 on the chart.
- Explain, "If I wanted to know what 2 times 7 was, I would count by twos 7 times." Demonstrate by counting seven circled boxes.
- Wipe clean and repeat with multiples of 5.
- Ask, "How can I figure out what 5 times 8 is?" Have students count with you as you count eight circled boxes to get to 40.

#### Guided practise

*(10 minutes)*

- Have students pair up and hand out a Skip Counting to 100 worksheet to each student.
- Guide students through one ‘round’ of the worksheet by skip counting to 100 by twos, colour coding each multiple.
- With their partner, have students skip count by three, colour coding the multiples as they count.
- Stop between each round of skip counting and ask students to use the numbers they colour coded on their chart to identify a product (i.e. what is 7 times 12?).
- Continue until all factors to nine are colour coded in different colors.

#### Independent working time

*(20 minutes)*

- Hand out the Skip Count to Multiply worksheet and review the example.
- Have students complete the worksheet independently.
- Circulate and offer support as needed.
- Go over the worksheet with the class.

#### Differentiation

**Support:**

- Provide a hundreds chart with some multiples highlighted and have students fill in missing multiples using skip counting.
- Review multiples of two, five, and 10 using the Skip Counting Chart worksheet.

**Enrichment:**

- Have students skip count starting at a number greater than 100 (i.e., skip count by threes, starting at 246).

#### Assessment

*(5 minutes)*

- In small groups of five to seven, have students skip count popcorn style by having each successive student shout out a multiple of a given number (i.e. student one says 6, student two says 12, student three says 18). Encourage students to skip count as high as possible.
- Listen in to groups to check for understanding.

#### Review and closing

*(5 minutes)*

- Show students the video of skip counting songs or teach them to sing along using a CD (see suggested media).
