Dot Cards as a Model for Teaching Number Relationships - Pg 142 - 143 (Chapter 8)

Dot cards are a set of cards (Blackline Masters) which contains:

1. dot patterns
2. patterns that require counting
3. combinations of two and three simple patterns
4. ten frames with "standard" patterns
5. unusual dot placements

(You can find Blackline Masters here: "http://lrt.ednet.ns.ca/PD/BLM/table_of_contents.htm")

Children use these cards for any activity that involves number concepts and develop thinking skills in young children. In the book, the author also suggested some activities which the teachers can use the dot cards for.

Activity 8.24 - Number Sandwiches (Using the dot cards):

1. Select a number between 5 and 12.
2. Students will need to find combinations of two cards that total that number. 
3. Place the two cards back by back and place them down with the dot side out.
4. Try to find at least 10 pairs and challenge the partner to name the number on the other side.
5. Flip the card over to confirm the answer.
6. The same pairs can then be used again to name the other hidden part.

Through this activity, children will learn the mathematical concept of:

1. Part-whole relationship.
2. Develop understanding of number concept.
3. Develop number bonds.
