red = 8 white = 5 blue = 1
When the same two numbers are added together, the result is always an even number, so B+B would be an even number ULESS C+C yielded an number that was greater than 9 causing a ten to be regrouped to the tens place value and making B+B+1 equal to an odd number. The value of E can be either even OR odd depending on the value of C+C.
The top row is the product of the two numbers in the middle and the bottom row is the sum of the two numbers in the middle. The missing numbers are
first puzzle box: 6
second puzzle box: 6 and 8
third puzzle box: 8
There are 8 solution combinations to this puzzle.
K-2 solution: 16 (the number above is doubled)
3-5 solution: 630 (each row within a column is multiplied by a value that increases by 1 on each row)
3x5=15 15x6=90 90x7=630
- What strategy did you need to determine the value of each color (replaced in the solution with like-colored hearts)?
- What was your starting place? (mine was seeing that I needed a double to equal the 9 in the tens place)
- Did you revise your thinking during the process of solving?
I originally thought the black icon had a value of 4. How did I know I needed to revise my thinking?
