15Counting in Groups Unit
Objective: Learn how counting in groups and repeated addition relate to multiplication This method of counting will help students
count 2-digit numbers. After “ten,” they can
How many are there? Count them to the song. count 2, 4, 6, 8 instead of 12, 14, 16, 18.
This is a helpful method if they forget which
two four six — eight — ten ten tens they are in.
two four six — eight — ten twenty
two four six — eight — ten thirty Have students count objects that are placed
irregularly in groups of 2.
Have students count as they draw the lines.
This will help them not miss any objects.
Some students will not count in groups of 2,
but will rather count them seperately. Since
the unit focuses on counting in groups of 2,
guide them to count in groups.
3. Check Point
Counting in groups of 2 will help students
easily approach multiples of 2 that will be
covered in the multiplication table.
