Counting Backwards (20-0)
Lesson Objective
Students will be able to (1) orally count backwards from 20-0 and (2) write numbers backwards from 20-0 in order.
Background Information for Teacher
Student Prior Knowledge
Student should be able to recognize numbers 0-20.
Ten stickers
21 pieces of large construction paper with a number (from 0-20) written in large print on each
index cards
Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
Step 2: Teach Lesson
The student can be seated on the rug close to the teacher. The teacher will begin by showing the student a sheet of stickers. There
should be 10 stickers on the sheet (stickers can be substituted with many other items). Together, the student and teacher will count
the stickers starting from 1 up to 10.
One by one, teacher will give a sticker to the student. After each sticker is removed, teacher will ask “How many stickers to do we
have left”?
By the time all stickers are passed out, the student would have counted down from 10-0.
Refer to a number line (or something similar) in the room. Notice how numbers get “bigger/greater” when counting forward and
“smaller/less” when counting backwards. Use hand/body gestures to refer to forward and backward.
Write the words “less”, “take-away” and “backwards” on the board or display the words on a pocket chart. Ask the student to tell you
what they know about those words. Together, chorally practice counting backwards from 20-0 as teachers points to each number on
the number line. Teacher can physically move backwards as the student count to show the relation.
Teacher should place pieces of large construction paper with one number (in order from 20-0) written in large print on each. The
student will pull small index card with a “mystery number” (0-20) written on it. The student will find their number on the construction
paper number line on the floor. They will then begin hopping/counting backwards from their mystery number.
Repeat until the student has pulled all the cards.
Recall sticker activity from the lesson's opening. Review the lesson with students. Ask students, "what did we learn about numbers
today"? Count backwards with students. Ask for questions.
Have the student complete the worksheet is Step 3.
