Unit 2

Standard 1: PATTERNS AND ALGEBRAIC REASONING: USE ALGEBRAIC METHODS TO DESCRIBE PATTERNS AND SOLVE PROBLEMS IN A VARIETY OF CONTEXTS

• 1.1 Describe rules that produce patterns found in tables, graphs, and models, and use variables (e.g., boxes, letters, pawns, number cubes, or other symbols) to solve problems or to describe general rules in algebraic expression or equation form.

Pan Balance Shapes – Easy version

Get different combinations of shapes to balance.  This is the easy one.

Pan balance Shapes – Harder version

The combinations are more complex here.

Standard 2: NUMBER SENSE: DEMONSTRATE AN UNDERSTANDING OF THE BASIC CONCEPTS AND PROPERTIES OF REAL NUMBERS

• 2.2a Basic Number Theory Concepts: Apply the basic properties of arithmetic: commutative, associative, distributive, and identity (e.g., show 2 (5 + 1) = (2 × 5) + (2 × 1), given (5 + 1) + (5 + 1) regroup to show this equals (5 + 5) + (1 + 1) concluding with (2 × 5) + (2 × 1)) to solve problems.

Standard 4: GEOMETRY AND MEASUREMENT: APPLY GEOMETRIC PROPERTIES AND RELATIONSHIPS AND USE MEASUREMENTS WITHIN THE METRIC AND CUSTOMARY SYSTEMS TO SOLVE PROBLEMS IN A VARIETY OF CONTEXTS

• 4.2 Find the perimeter of simple polygons and area of a rectangle (e.g., use 1-inch tiles to build rectangles of different perimeters and areas).
