Free Printable for Fun Addition Riddles
by David LaRochelle, illustrated by Brenda Sexton
1 + 1 =5 by David LaRochelle is perfect for some math fun towards the end of the school year or during summer school. This book is really a math riddle book which will delight children who already know basic math facts. For instance, one problem in the book is the same as the title, 1 + 1 = 5, and this is true when 1 set of triplets and 1 set of twins equals 5. Some of these problems would probably confuse children just learning addition, but most children would enjoy solving the problems. All of the problems in the book are 1 + 1, so they are based on one set of one kind of something or another.
Adults could present this book in all seriousness and not smile at first, and then surprise the students with some fun math.
I made a free animated Power Point of silly math riddles a little similar to the problems in the book, and a student work page so students may write their own math riddles. Happy math, Carolyn
