This packet includes flashcards for identifying how many counters are in a tens frame.
2 center activities for adding red plus yellow counters.
One center activity you would use red and yellow counters (Go Math Series uses these) put them in a cup and students will dump them out on the table. Then, students would write how many red and yellow counters there are on the lines provided and write the sum.
The second center activity is very similar. This activity will use the tens frame flashcards provided in this packet in order to create their addition sentences.
