Standards-based assessment and Instruction

## Bicycle Tires

There are 4 bicycles in front of the school. How many tires are there all together on the bicycles? Show and tell how you know..

### Alternative Versions of Task

#### More Accessible Version

There are 3 bicycles in front of the school. Each bicycle has 2 tires. How many tires are there all together on the bicycles? Show and tell how you know.

#### More Challenging Version

There are eight bicycles in front of the school. How many tires are there all together on the bicycles? Show and tell how you know.

### Counting and Cardinality Unit

The Counting and Cardinality Unit involves understanding numbers and how they are used to name quantities and to answer questions, such as:

• How many balls is the clown juggling?
• Do you have enough cups for each member of your group to have one?

### Exemplars Task-Specific Evidence

This task requires students to count to answer “how many.” Students also need to have
number sense to eight.

### TEKS Mathematical Process Standards
