BASIC 1 MATHEMATICS QUESTION 11

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 
 
Question focus: Identifying and correcting errors and omissions in counting or skip counting sequences (skip counting forwards by 1s)
  
Identify the correct skip count, errors and omissions by skip counting by 1s forward.
 
Example:
0, 2, 3, 5, 7, 8, 91
Correct Skip count: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Error: 91, this is an error because, instead of 9, 91 was written.
Omissions: 1, 4, 6, (These are omissions because they were not added to the set of numbers when you are skip counting by 1s forwards)
