Making a Difference Solving Word Problems
Digital Tool/Resource:
Word Problem Practice Game: "MOLLY ADDS & SUBTRACTS FROM 20"
Web Address – URL:
Overview:

This learning activity will provide online practice with solving word problems involving situations of adding to, taking from, taking apart, and comparing with unknowns in all positions. The students will use strategies they learned to solve the problems presented to them in this engaging online game. This is a helpful tool to measure the students' application of skills.

This activity results from the ALEX Resource Development Summit.

  Associated Standards and Objectives  
Content Standard(s):

MA2015 (2016)
Grade: 1
1 ) Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (See Appendix A, Table 1.) [1-OA1]


Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.1.1- Represent addition as "add to/put together" and subtraction as "take from/take apart" with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, or verbal explanations (limited to 15).

MA2015 (2016)
Grade: 1
2 ) Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. [1-OA2]

  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

  1. The student will use a computer to go to the website.
  2. The student will click on the arrow to begin listening to directions.
  3. The student will click on the arrow to enter the game to begin to play.
  4. The student will complete the tasks in the game.
  5. While the students are working, the teacher will monitor and check students' work for understanding and the use of learned strategies.
Assessment Strategies:

The teacher will observe the students while they play the game.  The teacher can use the following questions to guide his/her assessment of student progress toward mastering the standards:

  • Did the student move freely using the online manipulatives to solve the problems?
  • Did the student show an understanding of the problem presented?
  • Did the student apply knowledge from learning activities to solve story problems online?

Advanced Preparation:

  • Obtain internet-capable devices and/or computers for the students.
  • Make sure all have access to the website.
  • The teacher may want to have the exact game pulled up for students who may struggle using the computer.
  • The teacher will need to review before playing the game.
Variation Tips (optional):

  • Allow students to have paper and pencil for solving problems.
  • Allow students access to manipulatives for solving problems.
  • Allow students to work in pairs.
Notes or Recommendations (optional):

ALCOS 2019 Mathematics Standards:

1. Use addition and subtraction to solve word problems within 20 by using concrete objects, drawings, and equations with a symbol for the unknown number to represent the problem.
a. Add to with change unknown to solve word problems within 20.
b. Take from with change unknown to solve word problems within 20.
c. Put together/take apart with addend unknown to solve word problems within 20.
d. Compare quantities, with difference unknown, bigger unknown, and smaller unknown while solving word problems within 20.

2. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20 by using concrete objects, drawings, or equations with a symbol for the unknown number to represent the problem.

4. Explain subtraction as an unknown-addend problem.
Example: subtracting 10 - 8 by finding the number that makes 10 when added to 8

8. Solve for the unknown whole number in various positions in an addition or subtraction equation, relating three whole numbers that would make it true.
Example: determining the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ? – 3, and 6 + 6 = ?
