Content Source:

PBS
Type: Learning Activity

Overview:

Children will practice and explore strategies for solving addition and subtraction problems, such as using counters and rulers, performing mental math, and drawing pictures. As children encounter different outlandish scenarios with their PBS KIDS friends, they will explore, reinforce, and advance their addition and subtraction skills.

Content Standard(s):
Mathematics
MA2019 (2019)
Grade: 1
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.
Unpacked Content
Evidence Of Student Attainment:
Students:
  • Use a variety of representations to solve word problems.
  • Justify and explain answers using concrete objects and drawings.
Teacher Vocabulary:
  • Change unknown
  • Put together
  • Take apart
  • Compare
Knowledge:
Students know:
  • addition and subtraction strategies and models.
  • how to form an equation.
Skills:
Students are able to:
  • represent quantities and operations (addition & subtraction) with concrete objects, pictorially, or symbolically.
  • Use informal and mathematical language to communicate the representations.
  • Accurately compute sums and differences.
Understanding:
Students understand that:
  • addition is both putting together and adding to. subtraction is taking apart, taking from, and comparisons.
  • Mathematical problems can be solved using a variety of strategies. models, and representations.
  • variables in the form of blanks, boxes, or letters, represent unknown quantities when representing mathematical situations algebraically.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.1.1.1: Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
M.1.1.2: Understand key words in addition and subtraction word problems.
Examples: sum, difference, all together, how many more, how many are left, in all.
M.1.1.3: Define subtraction as separating groups of objects, taking from, or taking apart.
M.1.1.4: Define addition as combining groups of objects, adding to, or putting together.
M.1.1.5: Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
M.1.1.6: Represent numbers with objects or drawings.
M.1.1.7: Use objects to combine and separate groups.

Prior Knowledge Skills:
  • Define how many, all together, and in all.
  • Count to 20 by ones.
  • Demonstrate 1:1 correspondence.
  • Mimic counting objects in sequential order arranged in a line, circle, or array.
  • Count no more than 5 objects in a scattered configuration.
  • Mimic counting no more than 5 objects in a scattered configuration.
  • Count to 10 by ones.
  • Count in sequential order.
  • Mimic counting in sequential order.
  • Demonstrate one to one correspondence.
  • Make purposeful marks such as lines and circles.
  • Understand amount words, such as more, less, and another.
  • Begin to understand that parts of an object can make a whole.
  • Be interested in who has more or less.
  • Understand the concept of "less than".
  • Mimic counting by ones.
  • Recognize numbers from one to ten.

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 10).
