4. Operation Puzzle
Unit Overview
The basis of mathematics is numbers. Numbers and operations occupy a
majority of lower elementary curriculum because “numbers and operations”
are the foundation of mathematics. Regardless of its importance, it is also a
subject that is taught through mechanical calculations and repetition in which
students quickly lose their interest. This unit presents puzzles and activities to
help students gain a deeper understanding of the operations. These activities
will get students interested in the topic. The students will not only approach
the puzzles with fun and interest but they will also be able to build strategies
for problem solving by trial and error. Give the students ample time to
independently solve problems and to build self-confidence in their work.

Matrix Operations Puzzle Picture Operations Puzzle
Add each row and column to fill in with the sum. Use the number below each picture to find the sum or
difference.
EExxeerrcciissee Fill in the blanks with the correct number. + = The frog is 1 and the dog is 3,
so 1+3=4.
