Possible Resources	Mathematics, Houghton Mifflin Grade 2 (Anchor Text)
Nine Weeks Focus	Chapter 5,6, and 7 (pages 187-350) Adding and Subtracting Two Digit Numbers, Geometry, Fractions, and Probability
Skills/Standards (To teach and measure)	Number, Number Sense and Operations Standard C A 5. Represent fractions (halves, thirds, fourths, sixths and eighths), using words, numerals and physical models. For example: a. Recognize that a fractional part can mean different amounts depending on the original quantity. b. Recognize that a fractional part of a rectangle does not have to be shaded with contiguous parts. c. Identify and illustrate parts of a whole and parts of sets of objects. d. Compare and order physical models of halves, thirds and fourths in relation to 0 and 1. 9. Model and use the commutative property for addition. 11. Add and subtract multiples of 10. 12. Demonstrate multiple strategies for adding and subtracting 2- or 3-digit whole numbers, such as: c. informal use of commutative and associative properties of addition. 13. Estimate the results of whole number addition and subtraction problems using front-end estimation, and judge the reasonableness of the answers. Measurement Standard Geometry and Spatial Sense Standard 1. Identify, describe, compare and sort three-dimensional objects (i.e., cubes, spheres, prisms, cones, cylinders and pyramids) according to the shape of the faces or the number of faces, edges or vertices. 2. Predict what new shapes will be formed by combining or cutting apart existing shapes. 3. Recognize two-dimensional shapes and three-dimensional objects from different positions. 4. Identify and determine whether two-dimensional shapes are congruent (same shape and size) or similar (same shape different size) by copying or using superposition (lay one thing on top of another). 5. Create and identify two-dimensional figures with line symmetry; e.g., what letter shapes, logos, polygons are symmetrical? Pattern, Functions and Algebra Standard 3 4 5 6 7 8 9101112 1. Extend simple number patterns (both repeating and growing patterns), and create similar patterns using different objects, such as using physical materials or shapes to represent numerical patterns. 2. Use patterns to make generalizations and predictions; e.g., determine a missing element in a pattern. 3. Create new patterns with consistent rules or plans, and describe the rule or general plan of existing patterns. 4. Use objects, pictures, numbers and other symbols to represent a problem situation. 5. Understand equivalence and extend the concept to situations involving symbols; e.g., 4 + 5 = 9 and 9 = 4 + 5, and 4 + 5 = 3 + 6 = €+ž Data Analysis and Probability Standard 2. Read, interpret and make comparisons and predictions from data represented in charts, line plots, picture graphs and bar graphs. 7. List some of the possible outcomes of a simple experiment, and predict whether given outcomes are more, less or equally likely to occur. 8. Use physical models and pictures to represent possible arrangements of 2 or 3 objects.
