BASIC 3 || MATHEMATICS || QUESTION 2

STRAND 1: NUMBERS

SUB-STRAND 1: Counting, Representation, Cardinality and Ordinality
CONTENT STANDARD 1: Counting and estimate quantities from 0 to 10 000
INDICATORS AND EXEMPLARS 1: Use number names and the counting sequence to count and estimate quantities up to 10,000.
 
(E.g. 1. Skip count forwards and backwards from 0 to 10,000 by 10s, 50s 100s, 500s and 1000s starting at any point. Identify and correct errors or omissions in a skip counting sequence)
 
*Skip Count forwards by 10s
 
TIP/HINT: To skip count forward by 10s, add 10 to the number repeatedly.
Example: 10, 20, is the next number when you skip count forwards by 10s.
That is, 10 + 10 = 20. 

Now answer the questions below;
