Example: How many ways can you make the sum of 7 (4 red and 3 white, 5 red and 2 white, etc.) One thing I love to do with the Rekenrek is to push the red beads to the left and the white beads to the right and have students show me how many ways they can come up with a sum (by pushing the beads to the center). You also move the beads to the left and read it from left to right.

I put a sticker on the right side of the Rekenrek to help students know how to clear it.

we use the Danish Abacus as it works with our base-ten system (with 100 beads). Guess what? It is the same thing! So let’s get the lingo straight! What is an abacus? Most of you have heard of an abacus then the other day I saw it called a Ten Bar Demonstration Rekenrek. The more trained this pathway is, the more rapid their mental maths skills are.In math today, it seems like you finally understand what a new math tool is called and then you hear a new name and wonder if it is the same thing or something completely different. Because their ability to visualize and use their mental abacus is already sharp by this point in the training, they can read the numbers being flashed, compute, and answer the calculations almost instantly. When children do flash anzan, they are absorbing the numbers visually. The more fine-tuned our attention to detail is, the more aware we are and the quicker our recall. This is something we do without even trying. When we enter a room, we instantly take in information from our surroundings. Amplifying the auditory pathway for numbers develops brainpower and skills that take students to the next level.įlash Anzan: Anzan, which means mental math in Japanese, is practiced both with listening and flash. Listening to the numbers trains the brain much like reading does, except it uses a different pathway. The average adult has difficulty calculating without pen and paper because reading numbers have dominated their math journey. Listening: Just as the auditory pathway is developed at a young age to enable fluency in a language, the auditory pathway can be developed for numbers as well. The right hemisphere, which is the faster processor, then allows children to do incredibly fast mental calculations. The right hemisphere later uses this picture to create a mental image of the abacus. During this process, the eyes send a visual to the brain, placing a picture of the Soroban in their mind. Reading: When doing equations, children read the beads on the abacus.
