The purpose of this How Many Do You See? is for students to identify quantities represented with fingers. Students represent quantities with their fingers and work toward recognizing quantities presented on fingers without having to count. Students have an opportunity to notice and make use of structure because each hand has 5 fingers (MP7).
The purpose of this activity is for students to identify the group of objects that has more. This activity begins with a version of the Act it Out routine and builds on students’ work in the previous unit of answering “are there enough?” questions. In those lessons, students passed out, or matched up objects to determine if there were enough. Students build on this idea to help them determine which group has more objects.
The context of family mealtimes that is introduced in this activity will be revisited throughout the unit. Acting it out gives students an opportunity to make sense of a context (MP1). As students share about the tools that they use when eating with their families, record and save their responses to refer to and add to in future lessons. Consider reading picture books about family mealtimes. Some suggestions include:
Full, Full, Full of Love by Trish Cooke
Bee-Bim Bop! by Linda Sue Park
Yoko by Rosemary Wells
The Little Red Hen (Makes a Pizza) by Philomen Sturges
Rice & Rocks by Sandra L. Richards
The purpose of this activity is for students to learn Stage 2 of the Shake and Spill center. Students decide together how many counters to use (up to 10). They take turns shaking and spilling the counters. They compare the number of red and yellow counters and describe their comparisons.
As students shake and spill their counters multiple times, they have the chance to compare two groups of objects that have very different quantities as well as two groups of objects with very similar quantities. Students can compare the number of objects in the groups visually or by lining up and matching, as they did in the previous activity. Students may also count and use their knowledge of the count sequence to compare (“There are 7 red and 5 yellow counters. I know that 7 is more than 5.”). Students hear and repeat full comparison statements such as, “There are fewer red counters than yellow counters.” In making comparisons, students have a reason to use language precisely (MP6).

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:
Escoge un centro
Revuelve y saca
Dedos matemáticos
Fichas geométricas
Libros de imágenes
“Hoy aprendimos que, a veces, solo mirando podemos saber cuál grupo tiene más cosas, pero otras veces no podemos. Si solo mirando no pueden decir cuál grupo tiene más cosas, ¿qué pueden hacer?” // “Today we saw that sometimes we can figure out which group has more things by looking, but sometimes we cannot. If you can't tell which group has more objects by looking, what can you do?” (You can line them up and match them. You can count them.)
Hay 4 personas.
Hay 6 cucharas.
¿Cada persona recibe 1 cuchara?
If students compare the number of counters while the counters are still scattered, consider asking:
