Display the Math Practices page from the Reference
section of the Student Activity Book.
- What do you think it means to practice math? (Possible response: Solve problems; reason with
numbers; solve problems with numbers.)
- What do you think math practices means? (Possible response: things we do when we are
doing math)
Tell students that in this lesson students have been
focusing on getting to know a problem, Math
Practice 1, and choosing a strategy, Math Practice 2.
- Are you using any of these other math practices
when you problem solve? (Possible response:
Yes, I am adding labels to my number to show
what they mean; I check my answer to see if it
makes sense.)
Proficient problem solvers use all of the Math Practices each
time they solve a problem. Showing that these practices are
done is a bit more of a challenge for most problem solvers
and not every problem solving experience is an ideal opportunity
to observe every practice.
Use the Trading Cards Problems pages in the
Student Activity Book to assess students' abilities to
solve word problems. Have number lines, ten
frames, and connecting cubes readily available.
Students may draw their own part-whole diagrams if
needed.
Use the Trading Card Problems pages and the corresponding
Feedback Box in the Student Activity Book to assess students'
abilities to represent addition and subtraction situations
using multiple representations (e.g., counters, number
sentences, number lines, drawings, and ten frames) [E1]; use
mental math strategies and reasoning strategies (e.g., using
doubles, making ten) to solve addition and subtraction problems
within 20 [E2]; use addition and subtraction to solve
one-step word problems involving join, separate/take away,
part-whole, and compare situations [E3]; know what is
important to solve a problem [MPE1]; find addition and subtraction
strategies to solve problems [MPE2]; and show or
tell how to solve problems [MPE5].
Place the Show a Word Problem Master and the Animal Trading Cards Master in a center along with some connecting
cubes. Ask students to write and solve addition and subtraction
problems to provide targeted practice. Students can also
solve each other's problems.
