1.d. Round up to three-digit whole numbers to the nearest hundreds. (DOK 1)

1.e. Compare and order three-digit numbers using the symbols <, >, and =, and justify reasoning. (DOK 1)

1.f. Determine and compare the value of money up to $5.00 using the appropriate symbols for dollars and cents. (DOK 1)

MS.2. Algebra: Analyze patterns, numbers, relationships, and functions.

2.a. Explain, analyze, and extend repeating and growing patterns. (DOK 2)

2.c. Model situations and solve equations that involve the addition and subtraction of whole numbers. (DOK 2)

2.d. Analyze and generalize the inverse relationships between addition and subtraction. (DOK 2)

MS.3. Geometry: Describe, classify, and sort geometric figures according to their properties.

3.a. Recognize and identify polygons (rhombus, square, triangle, trapezoid, rectangle, pentagon, hexagon, octagon, and decagon) according to the number of sides. (DOK 1)

3.b. Describe the effects of composition and decomposition of polygons when smaller shapes are substituted for a larger shape or a larger shape is substituted for smaller ones. (DOK 2)

3.c. Identify and classify three-dimensional figures (cone, pyramid, and cylinder) according to their characteristics. (DOK 1)

MS.4. Measurement: Estimate, identify, and apply measurable attributes.
