2 Digit +/- with Regrouping.
“Animals of the Forest” is a Choosing the Operation Part-Part-Whole No Prep Game. No cutting or pasting needed. Pages can duplicated and used as games/ worksheets that can be done whole class, with groups, as partners, or independently.
The problems are worded carefully to include all common “Add-To” and “Take-From” situations: “Result Unknown”, “Change Unknown”, and “Start Unknown”. Part-Part-Whole questions include “Total Unknown” and “Addend Unknown”. Comparison questions are worded to address “Difference Unknown”, “Bigger Unknown”, and “Smaller Unknown”. Division problems address both “Group Size Unknown” and “Number of Groups Unknown”.
Part I: Read the Problem.
Part II: Part-Part-Whole
1. If the “Whole is Known”, write that number where it says “Whole”.
2. If you are “Looking for the Whole”, write a question mark “?” where it says "Whole".
3a. If both “Parts” are known, write them in the “Parts” section. (Addition)
3b. If only one part is known, separate the “Parts” section, write the known part and, on the unknown part write a “?”. (Subtraction)
3c. If there are several known equal parts, separate the “Parts” section of the PPW diagram into that many equal parts and write those known parts. (Multiplication)
3d. If there are several unknown equal parts, separate the “Parts” section into at least one or the number of those unknown parts and write “?” or “?s” in the parts. (Division)
“Different Values”, circle that with the “+” and “-“ sign. (Addition or Subtraction).
"Equal Parts”, circle that with the “x” and “÷” sign. (Multiplication or Division.)
“Looking for the Whole”, (Addition or Multiplication).
“Whole is Known”, (Subtraction or Division)
Circle the Correct Operation Sign ( + , - , x , ÷ ) and write it in the Circle. Computation may be done in margins and numerical answer written in circle also.
Trade and Grade. Give one point for each correct answer. There is one of each operation per page.
Structuring of the questions:
In “Animals of the Forest”, +/- 2 Digit Regrouping is used. Other Choosing the Operation Sets will have a varying levels of computational difficulty.
