The purpose of this activity is for students to learn Stage 2 of the Five in a Row center. Students take turns picking a number card and deciding to subtract 1 or 2 from the number on their card. They place a counter on that difference on the gameboard. The game ends when a player gets 5 counters in a row or the board is filled.

Some students may count back and some may count all then count back or remove 1 or 2 then count the remaining objects. Provide access to 10-frames and counters and encourage students to use them only if needed.

Students should remove cards that show 0 from their deck before playing. The gameboard will be used again in upcoming lessons. Consider copying it on cardstock or laminating it for future use.

• “Tengo el número 8 y quiero restar 2. ¿Cómo puedo hacerlo?” // “I have the number 8 and I want to subtract 2. How can I do it?”
• Invite previously identified students to share.
• “¿En qué se parecen estos métodos? ¿En qué son diferentes?” // “How are these methods the same? How are they different?” (They all take away 2. They subtract in different ways.)

The purpose of this activity is for students to choose from activities that focus on counting up to 20 objects or adding and subtracting within 10. Students choose from the centers introduced in previous lessons as well as the center introduced in the previous activity. If more than one stage of a center has been introduced in this grade, students can choose from any of those stages. Students are encouraged to choose the center that will be most helpful for them at this time.
