3.Three consecutive integers are involved. The sum of the first, triple the middle, and four times the largest is 131. Find the integers.
 
4. Find the maximum volume of a rectangular box with a square base at least 1 cm by 1 cm if its surface area is 600 cm2.
 
5. Compute the area of the figure.


 
The Math Class Languages
 
 
 
 
 
 
 
 
Please discuss your answers with your partners.
 
Discuss This With Your Partner, DTWYP,
  • Teaches students to confer with others in order to gain knowledge.
  • Permits student who are stronger to assist the weaker and feel better about their own expertise.
  • Permits the weaker to be in command of their own education by seeking help.
  • Permits students to communicate mathematics in the mother tongue, in other tongue(s), in formal spoken mathematics and in informal spoken mathematics

Closing Remarks
  • Discuss This With Your Partner is the most valuable strategy!
     
  • Introduce in the Most Concrete
    in the Mother Tongue when possible
    at the earliest opportunity
    repeat the message in summary or with a picture
    then, later, formally introduce the topic

  • Debrief in the Most Abstract
    DTWYP!
    Visualize, Verbalize, thenWrite
    in the Mother Tongue after Formal Mathematics

  • Regularly Require Translation from One Language to Another
    Use tiles and words and symbols alone and together

  • Good Stories Are Worth Retelling.
     
  • Retell your mathematical stories in as many languages as possible.
