Number Sense & Numeration
Math: Problem solving using Greg Tang's Math Appeal |
| |
|
2. Content-
|
| addition, subtraction, more than, less than, altogether, how much
is left over. |
| |
|
3. Goals: Aims/Outcomes-
|
1.to get them to learn the concept of problem solving
2.to have students use subtraction to add and simplify problems through
patterns and symmetries
3.to have a small group of students discover different ways of solving
problems, confidently finding what works best for them |
| |
|
|
4. Objectives-
|
1.watch to see if they need help. If they don't need any help try
moving on to harder problems.
2. observe ways that students demonstrate their learning
3. observe how students explore concepts and assess what level of
complexity they will perform procedures |
| |
|
5. Materials and Aids-
|
1.Greg Tang's Math Appeal, Scholastic Press, New York, 2003
2.Chart Paper & Markers
3.Number Line (created by students)
4.Base 10 Blocks |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1.Read the Greg Tang's Math Appeal to the students
2.Talk about each problem on the page and discuss the hints that are
provided to assess the students understanding of the riddle provided
3.Ask the students if they can "see" another way of solving the problem,
discuss as a group |
| |
|
|
B. Development-
1.Using manipulatives discuss solving problems via patterning and
grouping of numbers
2.Show the students an example of solving a problem on the chart paper
3.have the students draw a number line on a separate chart paper to
use as needed |
| |
|
|
C. Practice-
1.Take the first problem in the book and ask the students to solve
it together as a group (teacher included)
2.Do one of the problems in the book as a group without teacher assistance/guidance
3.Have students complete one solution on their own and do a teacher
check |
| |
|
|
D. Independent Practice-
1.Observe students solve a problem on their own
2.Have students re-read the problems in the book and choose a riddle
to solve
|
| |
|
|
E. Accommodations (Differentiated Instruction)-
1.Remind students to make sure to look for the key words in the
problems. How much is left? altogether?
2.Make sure the number line is available to all students reminding
students that it is there as an aid that it is OK to utilize the number
line if needed
3.Provide extra time to any student as required and offer to clarify
any wording to assist in the understanding of the riddle |
| |
|
|
F. Checking for understanding-
1.make sure that students know how to add using subtraction before
they leave. Ask them if they have an misunderstandings or question's
about the lesson.
2.Ask if they are comfortable with their understanding of the problems
and the solutions
3.Ask students to retell a way that they found the solution to one
of the riddles |
| |
|
|
G. Closure-
1.Reiterate students successes and remind students of success criteria
2.Thank students for their time, and remind them that they helped
me learn just as I know through their questions and answers that they
have learned something new too. |
