ACTIVITY 2 – NUMBER OF DIGITS AND THEIR PLACE VALUES 10 – 99
10 11 12 13 14 15 up 99
10 – 1 and 0 – 2 digits – place value, Ten and Unit
11 – 1 and 1 – 2 digits – place value, Ten and Unit
13 – 1 and 3 – 2 digits – place value, Ten and Unit
14 – 1 and 4 – 2 digits – place value, Ten and Unit
15 – 1 and 5 – 2 digits – place value, Ten and Unit
Randomly choose a number on the chart and continue the flow.
For example,
26 – 2 and 6 – 2 digits – place value, Ten and Unit
30 – 3 and 0 – 2 digits – place value, Ten and Unit
44 – 4 and 4 – 2 digits – place value, Ten and Unit
78 – 7 and 9 – 2 digits – place value, Ten and Unit
89 – 8 and 9 – 2 digits – place value, Ten and Unit
92 – 9 and 2 – 2 digits – place value, Ten and Unit
99 – 9 and 9 – 2 digits – place value, Ten and Unit
