KenKen was born in a math classroom as a tool to promote computational fluidity in a fun and addictive way. Students develop their math and logical thinking skills without even knowing it. Bring Kenken puzzles to your students, from easiest to super hard, for FREE! (They have a section just for teacher).

yohaku logo.jpg

A yohaku is a type of number puzzle that will test your number sense and problem solving skills. Each yohaku is either an additive or a multiplicative puzzle (as indicated by the symbol in the bottom right of the grid). Your task is to fill in the empty cells such that they give the sum or product shown in each row and column.

Great for use in classrooms as a lesson starter, or for the morning commute, or for something to accompany an afternoon cup of tea. Some yohakus will take a few minutes to solve, others will have you puzzling for longer (and you're welcome).

Each yohaku is lovingly created by hand!
