Numbers 15-20: Recognizing Groups of 5

    The students drew a number between 15 and 20 from a bag. Then they made the number on their ten frame. Then they made towers of 5 and shared with their partner how many towers of five and how many left over they had to equal the number they drew.

    They also drew numbers 15-20 from a bag and then made the number using towers of five with their partner.

    The students played number concentration, matching a number card with the matching dots. They also talked about the groups of fives they saw on the dot patterns.

   The students drew numbers 15-20 from a bag and worked with their partner to represent the number using their fingers. They worked at their tables; then came to the carpet. I told each pair a number and they had to show us the number with their fingers.

Numbers 15-20 on Ten Frames

        We've been working on identifying and creating sets using numbers 15-20 on ten frames. I taped off two ten frames on our classroom floor. We started by using flashcards to review numbers 1-15. Then I mixed the cards up and held up a card, the students had to identify it, and work together to represent that number using themselves on our ten frames. They loved being the math "manipulative" and were all so quiet and still because they each wanted a turn. 

    After making about half the numbers using the students as the manipulative. We went back to our tables and I passed out ten frames mats to the students and a different manipulative to each table. Then I held up a number, and the students had to identify it and represent it on their ten frame.

    Then students took turns calling out numbers at their tables and representing that number on the ten frames. After they made the number and counted to check, the caller checked their work as well.
