1+1=5: and Other Unlikely Additions

How much is 1+1? Think the answer is 2? Not always, as this playful approach to addition proves! David LaRochelle takes children on a joyful mathematical journey that will engage their minds and teach them to think about numbers in a creative, outside-the-box way.
Brenda Sexton's wild and wacky illustrations add layers of witty fun to LaRochelle's clever game.

These wacky equations don't add up…or DO THEY?
1 goat + 1 unicorn = 3 horns!
1 set of triplets + 1 set of twins = 5 babies!
1 duet + 1 quartet = 6 musicians!
1 ant + 1 spider = 14 legs!
1 century + 1 decade = 110 years!
