BASIC 1 MATHEMATICS QUESTION 2

Strand 1:  NUMBER

Sub-Strand 1:  Number: Counting, Representation, Cardinality & Ordinality
CONTENT STANDARDS 1: Describe numbers and the relationship between numbers 0 to 100
INDICATORS AND EXEMPLARS 1: Use number names, counting sequences and how to count to find out “how many?”
 
E.g. 1.  Count by 1s (forwards and backwards) between two given numbers between 0 and 100; or by 2s and 10s; Identify and correct errors or omissions in counting or skip counting sequences 
 
-Skip count Backward by 1s

 

Using the table below as a guide, fill in the missing numbers by counting backwards by 1s

1. 50, ___, 48, ___, 46, ___

2. 10, ___, ___, 7, 6, 5, ____

3. 16, 15, ____, ____, 12, ____

4. 36, 35, ____, ____, 32, 31, ____,

5. 99, ___, 97, 96, ____, ____, 93
 

State whether it is True or False

 
6. When counting backwards by 1s , if you are from 96 the next number is ­­­­94.
True / False

7. From 20, the next number is 21 when counting backwards by 1s.
True / False

8. 99 when counting backwards by 1s will give you 98.
True /False

9. Counting backwards by 1s, if you are from 11 the next number is 12.
True / False

10. From 8 the next number is 9 when counting backwards by 1s.
True / False

Complete the table below by counting backwards by 1s with the correct value of the numbers which are represented by the letters of alphabet.

1. 49, 47, 45

 

2. 9, 8, 4

 

3. 14, 13, 11
