# GR. PK Unit: Lesson Seed: COUNTING TO FIND OUT "HOW MANY"

**Essential Questions: **

• What do numbers convey? (identify amount--Cardinal; name position --ordinal; indicated location --nominal)

• How can numbers be expressed, ordered, and compared?

• What are different ways to count? ( count all, count one, count back, skip count, count groups)

• What are efficient ways to count? (count up, (or back) from largest number, count sets of items, count to/using landmark numbers)

• How can numbers be decomposed into other numbers or composed into another number?

Lesson seeds are ideas that can be used to build a lesson aligned to the CCSS. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction. When developing lessons from these seeds, teachers must consider the needs of all learners. It is also important to build checkpoints into the lessons where appropriate formative assessment will inform a teachers instructional pacing and delivery.

**Standard(s):**

Standard: PK.CC.B.4a: When counting objects, say the number names in the standard order, pairing each object with one and only one number name.

**Purpose/Big Idea:**

Meaningful counting integrates different aspects of number and sets, such as sequence, order, one-to-one correspondence, ordinality, and cardinality.

##### Guiding Questions:

**How many counters do you have?**

**How do you know how many counters you have? Are you sure?**

**Why are you sure?**

**How many objects have you touched?**

**How do you know how many objects you touched?**

**Is it okay to say two number names when you touch a counter?**

**Was it easy to count the objects in the circle?**

**Was it easy to count the objects in a row on the line?**

**Was it easier to count the objects when they were in the circle or lined up in the row?**
