Students collaborate to create norms for their work together. They are encouraged to share their ideas and listen to the ideas of others, to make connections, and to see themselves as...

In this section, students continue to explore numbers and quantities in their classroom, focusing on small groups of objects or images they can quantify without counting. They match groups that have the same number of images and notice that the same quantity can be arranged in many different ways. Students continue to develop the language to express these ideas and...

In this section, students focus on counting up to 10 objects and answering “how many?” questions. They learn a new routine, Questions about Us, and consider the question “how many of us are here today?” The routine offers opportunities to highlight one-to-one matching and keeping track of what is being counted.

Students also count collections of objects from the...

In this section, students work on the concept of one-to-one correspondence. They match one object to one person or image to answer “are there enough” questions and to gather objects. This matching skill will be useful in the next section and in future counting when students match one number word to one object.

“Are there enough?” and “can you get...
