Lesson 5

Lesson Plan #5:  2s, 9s and 10s Count Bys

Performance Objective: Given a worksheet, students will correctly answer 2s, 9s, and 10s count-bys and multiplications 9 out of 10 times.

Resources or Materials Needed: Worksheet, pencil

Time: 60 minutes 

Step 1: Pre-Instructional Activities: Begin this lesson by reviewing multiplication with the factor of 5.  Ask the students to close their eyes.  Ask them to say the answer the equaition 3x5.  The class should say in unison “15.” Repeat with a few more equations that have a factor of 5.  Then explain that today we are going to learn multiples of 2s, 9s, and 10s. 

Step 2: Content Presentation: Begin instruction as a whole group and end with independent work to check for understanding.  

Step 3: Learner Participation: After the reviewing multiplication problems with a factor of 5, ask “What are some strategies you used to figure out the answer?” Responses may include count bys,  repeated addition, or drawing a picture such as an array or multiple groups. Reinforce these concepts by practicing with the number two.  Remind students that there are multiple ways to find the answer, and any of them will work.  When students get the hang of twos repeat with nines and tens. 

Step 4: Assessment: Multiplication worksheet (See Appendix E)

Step 5: Follow-Through Activities: After the students have practiced using count bys, repeated addition, multiple groups drawing, and arrays drawing, show them the quick way to multiply by nine by using fingers. Show them by holding out both hands and telling them to invision there are numbers above each finger.  To find a number times nine, bend down the finger for that number.  Do a few examples for them to watch.  To find 5x9, bend down your fifth finger.  The fingers to the left of the bent finger are the tens and the fingers to the right are ones.  For this problem, there are 4 fingers to the right, and 5 fingers to the left.  Repeat with a few more examples and invite the students to try themselves.

Lesson Plan Summary: Start the lesson grasping the students attention by having them close their eyes.  This is something different that will help them pay attention and focus on a task in a fun way.  Begin in a large group and end instruction with individual work to meet the needs of each student.  These instructional strategies support the learning theory of Behaviorism because students practice what they’ve learned through repetition.
