Rote Counting Skills From 100 to 1

By

Maloney Einstein

Rationale:

In this exercise, we reverse the previous exercises to teach rote counting from 100 to 1. We will practice counting until the fluency level of 150 counts/minute with 2 or fewer errors is reached. First we will teach the students with the model available (See/Say Counting Backwards from 100-0). In the next task we will teach the students to count backwards from 100-0 without a model. (Think/Say Counting Backwards from 100-0)

Materials:
The numbers from 1 to 100 printed below.

 

  1   2   3   4   5   6   7   8   9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
51 52 53 54 55 56 57 58 59 60
61 62 63 64 65 66 67 68 69 70
71 72 73 74 75 76 77 78 79 80
81 82 83 84 85 86 87 88 89 90
91 92 93 94 95 96 97 98 99 100

Rote Counting from 100 to 1. See and Say Numbers from 100 to 1.
This task should be done for a couple of minutes each day until the student counts from 100 quickly and easily without errors.  Notice that the display is set out using recursive numbers so that the student can see the pattern for counting by 100s to 1.

Note: Notice that the display did not change from the last task of counting by 1s to 100.  We want to present the learner with as few changes as possible. The difference is that the student will start at the bottom right corner of the display and work backwards, changing lines each time that they say a group of 10 numbers.

 Say to the students, Now we are going to learn to count backwards from 100 to 1.

This will help you when you learn other arithmetic tasks. 

 Touch the number 100 on the bottom line of the display.

I am going to count backwards from 100 to 90. Listen. 100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90.

Listen Again. 100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90.

 Count backwards with me from 100 to 90. When I touch the numbers we will both say them. Ready. Signal.

Teacher and students say, 100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90.

 Let’s do that one more time. Ready. Signal.

Teacher and student say,   100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90.

Excellent counting. Now do that all by yourself. Put your finger on the number 100 and count backward to 90. Ready. Signal.

 Students say,            100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90.

Repeat Task 1 for sets of numbers 90- 81,  80 -71, 70-61, 60 – 51, 50 – 41,  40 -31, 30 -21, 20 – 10, and from 10 – 0.

When the students can say any single line quickly and without errors, you can begin to chunk the task into large units e.g. Now we are going to count from 100 to 80. Ready. Signal.

Continue to make the chunks larger as the students demonstrate their ability to work quickly and accurately on the task.
