Lesson Plan

St. Thomas the Apostle School

Second Quarter (November - January) 2007

 

Grade:            2

Teacher:         Miss Kimberly Miller

Subject:          Mathematics

Unit 3:             2-Digit Addition and Subtraction

 

Mathematics for the Year:

All schools in the Diocese of Albany now use the latest edition of the Archdiocesan Essential Learnings for Mathematics.  At St. Thomas we have math textbooks to use as a resource, but they don't dictate what we teach or when we teach it.  **Unit 2:  Money and Time will be taught third quarter.

 

Content Strands for the Second Quarter:

            þ Already taught or introduced                     Still need to teach or introduce

þ        2.N.3          Skip count by 3's to 36 for multiplication readiness

þ        2.N.6          Develop an understanding of the base ten system: 10 ones = 1 ten   

                   10 tens = 1 hundred  10 hundreds = 1 thousand

þ2.N.7   Use a variety of strategies to compose and decompose two-digit numbers

                   þ  NB:  Decompose is a process to break a number into smaller units to            

                         simplify computation.

                   For example, 36 = 30 + 6.

                    Compose is part of a process of grouping decomposed numbers that are                

                easier to compute.

                  For example.        36 = 30 + 6

                                           + 23 = 20 + 3

                                                      50 + 9

                                                        59        

þ        2.N.13     Recognize the meaning of zero in the place value system (0 -100)

þ        2.N.15     Determine sums and differences of number sentences by various means              

(e.g., families, related facts, inverse operations, addition doubles, and doubles plus one)

   2.N.16      Use a variety of strategies to solve addition and subtraction problems using   one- and two-digit numbers with and without regrouping

   2.N.18      Use doubling to add 2-digit numbers

   2.N.19      Use compensation to add 2-digit numbers

NB:    Compensation is a strategy that can be used for addition which usually involves increasing one addend while decreasing the other by the same amount. For example, when adding 46 + 38, add 2 to 38 to make 40 and take two away from 46, resulting in 44; then add 40 +44 to get 84.

þ        2.A.1                    Use the symbols <, >, = (with and without the use of a number line) to compare whole numbers up to 100

  2.G.3  Compose (put together) and decompose (break apart) two-dimensional shapes

   2.G.6 Explore line symmetry

   2.M.2        Use a ruler to measure standard units ( whole inches and whole feet)

þ   2.M.4        Recognize mass as a qualitative measure (e.g., Which is heavier? Which    

                      is lighter?)

þ   2.M.5 Compare and order objects, using lighter than and heavier than

þ   2.S.2        Collect and record data (using tallies) related to the question

þ   2.S.3        Display data in pictographs and bar graphs/pie charts using concrete     

objects or a representation of the object

NB:  A pictograph is a graph that uses pictures or symbols to represent data.   An accompanying key indicates the value associated with each picture or symbol. A bar graph is a graph that uses horizontal or vertical bars to display data.

                 example of picto - 1 car picture = 5 cars

                   A Pie (circle) graph is a graph in which the data is represented by sectors        of a circle. The total of all the sectors should be 100% of the data.

 

Description:

 

Daily hands-on instruction, classroom discussion, small group instruction and practice in the mathematics workbook will take place in all the above listed content strands.  Mrs. Wolfgang will reinforce concepts during math lab.

 

Assessment:

 

Daily teacher observation during instruction will take place.  Timed addition and subtraction tests will be given frequently.  There will be at least six unannounced quizzes given to assess progress and one unit test.

 

Report Card: 

Daily work 35%  Participation 10%  Homework 10%  Testing/Evaluation 45%

 

Homework Assignments and Help from home:

 

Written math homework will be assigned as needed one or two times weekly.  In addition to these formal assignments students are expected to practice addition and subtraction facts up to and including 20.

 

Completed class work is sent home after students have corrected the majority of errors in school.   Parents are asked to review these papers as needed at home; please do not return these papers to school.  **Incomplete work without a note from me should not be coming home.

 

Completed math tests and evaluations are placed in the front pocket protector of the Yellow Test Folder.  Please examine these papers, initial, and return them to the pocket protector so that they are available for future reference in school.
