The purpose of this Warm-up is for students to practice the verbal count sequence to 10 and show quantities with their fingers.

• “Cuenten hasta 10 con su pareja. Un compañero dice los números del 1 al 10 mientras el otro levanta sus dedos” // “Work with your partner to count to 10. One partner says the numbers from 1 to 10 while the other partner puts up their fingers.”
• Switch roles.

The purpose of this activity is for students to notice that the arrangement of a group of objects does not affect the number of objects. Students grab a handful of up to 10 connecting cubes and count to see how many they have. They then rearrange the connecting cubes using a 5-frame and discover that although the connecting cubes are arranged differently, the number of connecting cubes stays the same. This understanding develops over time with repeated experience working with quantities in many different arrangements. Students may continue to recount the objects in this and future lessons until they understand and are confident that the number of objects remains the same when they are rearranged.

The purpose of this activity is for students to learn Stage 1 of the Shake and Spill center. Students shake and spill 6–10 counters. Because the counters will be scattered when they are spilled, students will likely rearrange the counters to make them easier to count. Both partners count the counters, which allows them to confirm that they have counted accurately. 

As students shake and spill the same number of counters multiple times, they notice that the number stays the same each time. After multiple rounds, students may not need to recount the counters to state how many there are. When students notice a pattern or repetitive action in computation, they look for and express regularity in repeated reasoning (MP8).

The purpose of this activity is for students to choose from activities that offer practice with number and counting concepts.

Students choose any previously introduced stage from these centers:

• Shake and Spill
• Math Fingers
• Pattern Blocks
• Picture Books
