Missing Numbers
(OA-Primary)
You Need: A hundreds chart with
numbers that are removed. A
classroom pocket chart is good to use.
Directions:
1. The students’ task is to replace the missing
numbers in the chart. Beginning versions of
this activity have only a random selection of
individual numbers removed.
2. Later, remove sequences of several numbers
from three or four different rows.
3. Finally, remove all but one or two rows or
columns.
4. Eventually, challenge children to replace all of
the numbers in a blank chart.
Is It More or Less?
(OA-Primary)
You Need: Deck of playing cards (without face cards)
Directions:
1. Each player chooses one card and displays it.
2. Players say the more than, less than, or equal to
statement. For example, “Seven is more than fie.”
3. The player who has the greater number takes
both cards.
4. If the cards re equal, each player keeps her/his
own card.
5. Continue playing through the deck.
6. The winner is the player with the most cards.
Questions to ask students as they are playing:
1. Which card is less than the other card?
2. How much more is the greater number?
3. How close are the cards to being equal?
Challenge: Choose two cards and add the numbers
together.
