二年級數學（第 25-32 週）

This is a continuation of 2nd Grade Math (weeks 1-8), 2nd Grade Math (weeks 9-16), and 2nd Grade Math (weeks 17-24). It is recommended that you take weeks 1-24 before taking this class. 

In this class I will be teaching the forth quarter of 2nd grade math. I will be using the common core standards.

***This class will only run if there are at least 2 students. 

In this class students are encouraged to ask questions and discuss and explain problems. Students will get many opportunities to participate in this class. My goal is to help my students love math.

Lesson 1: Sort and record data into a table using up to four categories; use category counts to solve word problems. Lesson 2: Draw and label a picture graph to represent data with up to four categories.
Lesson 3: Draw and label a bar graph to represent data; relate the count scale to the number line.
Lesson 4: Draw a bar graph to represent a given data set.
Lesson 5: Solve word problems using data presented in a bar graph.
Lesson 6: Recognize the value of coins and count up to find their total
value.
Lesson 7: Solve word problems involving the total value of a group of
coins.
Lesson 8: Solve word problems involving the total value of a group of
bills.
Lesson 9: Solve word problems involving different combinations of coins with the same total value.
Lesson 10: Use the fewest number of coins to make a given value.
Lesson 11: Use different strategies to make $1 or make change from $1.
Lesson 12: Solve word problems involving different ways to make change from $1.
Lesson 13: Solve two-step word problems involving dollars or cents with totals within $100 or $1.
Lesson 14: Connect measurement with physical units by using iteration with an inch tile to measure. Lesson 15: Apply concepts to create inch rulers; measure lengths using
inch rulers.
Lesson 16: Measure various objects using inch rulers and yardsticks.
Lesson 17: Develop estimation strategies by applying prior knowledge of length and using mental benchmarks.
Lesson 18: Measure an object twice using different length units and compare; relate measurement to unit size.
Lesson 19: Measure to compare the differences in lengths using inches,
feet, and yards.
Lesson 20: Solve two-digit addition and subtraction word problems involving length by using tape diagrams and writing equations to represent the problem. Lesson 21: Identify unknown numbers on a number line diagram by using the distance between numbers and reference points.
Lesson 22: Represent two-digit sums and differences involving length by using the ruler as a number line.
Lesson 23: Collect and record measurement data in a table; answer
questions and summarize the data set. Lesson 24: Draw a line plot to represent the measurement data; relate the
measurement scale to the number line.
Lessons 25–26: Draw a line plot to represent a given data set; answer questions and draw conclusions based on measurement data.

Module 8-
Lesson 1: Describe two-dimensional shapes based on attributes.
Lesson 2: Build, identify, and analyze two-dimensional shapes with specified attributes.
Lesson 3: Use attributes to draw different polygons including triangles, quadrilaterals, pentagons, and hexagons.
Lesson 4: Use attributes to identify and draw different quadrilaterals including rectangles, rhombuses, parallelograms, and trapezoids.
Lesson 5: Relate the square to the cube, and describe the cube based on attributes.
Lesson 6: Combine shapes to create a composite shape; create a new shape from composite shapes.
Lessons 7–8: Interpret equal shares in composite shapes as halves, thirds, and fourths.
Lessons 9–10: Partition circles and rectangles into equal parts, and describe those parts as halves, thirds, or fourths.
Lesson 11: Describe a whole by the number of equal parts including 2 halves, 3 thirds, and 4 fourths.
Lesson 12: Recognize that equal parts of an identical rectangle can have different shapes.
Lesson 13: Construct a paper clock by partitioning a circle into halves and quarters, and tell time to the half hour or quarter hour.
Lesson 14: Tell time to the nearest five minutes.
Lesson 15: Tell time to the nearest five minutes; relate a.m. and p.m. to time of day.
Lesson 16: Solve elapsed time problems involving whole hours and a half hour.
