### Overview

Children will practice and explore strategies for solving addition and subtraction problems, such as using counters and rulers, performing mental math, and drawing pictures. As children encounter different outlandish scenarios with their PBS KIDS friends, they will explore, reinforce, and advance their addition and subtraction skills.

## UP:MA19.1.1

### Vocabulary

• Change unknown
• Put together
• Take apart
• Compare

### Knowledge

Students know:
• addition and subtraction strategies and models.
• how to form an equation.

### Skills

Students are able to:
• represent quantities and operations (addition & subtraction) with concrete objects, pictorially, or symbolically.
• Use informal and mathematical language to communicate the representations.
• Accurately compute sums and differences.

### Understanding

Students understand that:
• addition is both putting together and adding to. subtraction is taking apart, taking from, and comparisons.
• Mathematical problems can be solved using a variety of strategies. models, and representations.
• variables in the form of blanks, boxes, or letters, represent unknown quantities when representing mathematical situations algebraically.
