Grade 2 Bridge: Equal Groups, Odd/Even, and Arrays

How the lesson starts: Grade 2 Bridge: Equal Groups, Odd/Even, and Arrays

1. Penguin dance party

   Hi friend! Welcome to the penguin dance party! Every penguin wants a dance buddy. Can everyone find a partner? Let's check!

2. Pairs or one left over

   8 penguins make 4 pairs. Nobody is left over! 8 is even. 7 penguins make 3 pairs, and one is alone. 7 is odd. Even numbers end in 0, 2, 4, 6 or 8.

3. Check the last penguin

   Can 15 penguins pair up with none left? Make pairs. 7 pairs, and one left over! So no. 15 ends in 5. Odd! Watch out! Big numbers are not always even.
