In this short guide you will be able to preview the segment. You’ll also get some great ideas for in-class activities after watching the video with your students.

Here are 2 creative and fun in-class activities for before/after watching the video…

Breaking the Code

The table, Code Breaker, gives a value to each letter in the alphabet: A=1, B=2 etc. Using the Code Breaker, your students will have to solve the following three challenges –

1.

Spell your favorite color

For example, the color BLACK= 2,30,1,3,20

2.

Find out who the famous person is…

5, ___, 50, 100, 200, ___, 2, 50*

*The missing numbers are an extra challenge.
(The answer: Einstein.)

3.

Select a name of a state/city
and present it by math operations

For example, the state of Florida:
 2×3; 60÷2; 25×2+10; 180÷2; 3×3; 36÷9; 1×1

Open the Safe

Solution

To solve this tricky challenge, we use the elimination strategy:

1.

2.

3.

4.

5.

6.

The 4th clue tells us that the numbers 3, 7 and 2 won’t be used. (0,1,4,5,6,8,9 are still optional)

5th clue – since 7 and 2 can’t be used, number 5 must be used in the first or second place.

1st clue: we eliminate the 2 and we know that 4 or 8 will be used: if it’s 8 it must be in third place, and if it’s 4 it must be in first place.

When checking the 2nd clue it’s clear that number 4 can’t be in first place, (because it contradicts the 1st clue)…so we eliminate number 4 and it is now clear that number 8 must be the third digit. (we also know that 9 or 6 will be used but not in their current places)

3rd clue – Since we eliminated number 4, we know that both 8 and 5 will be used. If 8 is in third place, 5 must be in first place.

So which digit will be in the middle? Back to the 2nd clue, we know that 9 or 6 will be in the middle. However, since 9 can’t be in the middle, we know that it must be number 6.

Conclusion

The correct digits:
5, 6, 8

After watching the Teacher’s Guide it is time to share the
“Wish on a Golder Fish”
with your students in class.
