The purpose of this Warm-up is for students to consider concepts of number in a familiar context. The Synthesis focuses on knowing that 1 more is the next counting number.
The purpose of this activity is for students to find groups that have more images than a given group. Students can compare in any way that makes sense to them. Students describe the comparisons using “more,” “fewer,” or “the same number.” In the Activity Synthesis, students use mathematical vocabulary precisely to discuss how different ways of counting can help to compare the number of images in groups (MP6).
Fewer, Same, More Stages 1–4 Mat, Spanish
Fewer, Same, More Stages 2 and 3 Cards
The purpose of this activity is for students to learn Stage 2 of the Fewer, Same, More center. Students choose a card with an image and place it in the box at the top of the mat. They take turns picking another card, deciding if the image shows fewer, the same, or more than the original amount, and placing the card on the correct box on the mat. The cards show groups of images in different arrangements.
The Activity Synthesis highlights the idea that numbers that are fewer than 5 come before 5 in the count sequence and numbers that are more than 5 come after 5 in the count sequence. This idea will be revisited in future sections and units. Students need repeated experiences comparing groups of objects, images, and numbers to be able to notice, articulate, and use the connection between the counting sequence and comparing the size of numbers (MP7, MP8).
In this activity, students place a card with 5 images at the top of their mat. During center choice time, students can place any card at the top of their mat.
MLR8 Discussion Supports. Remind students to use comparison language such as “menos que”, “el mismo número que”, “más que” // “fewer than,” “the same number as,” “more than.”
None
The purpose of this activity is for students to choose from activities that offer practice counting and comparing groups of objects and images.
Students choose from any previously introduced stage from these centers:
Escoge un centro.
Menos, lo mismo, más
Bingo
Historias matemáticas
Cubos encajables
Carrera con números
Display or draw this image for all students to see.
“Hoy contamos y comparamos el número de cosas que hay en grupos. ¿Cómo les ayuda esta imagen a ver que 7 es más que 4?” // “Today we counted and compared the number of things in groups. How does this picture help you see that 7 is more than 4?” (I can see that 7 has 4 and then some more.)
“Practiquemos cómo contar hasta 20” // “Let’s practice counting to 20.”
Demonstrate counting to 20. Count to 20 as a class 1–2 times.
