# Manipulatives - Using Japan Math Block Sets

### What is it? Essential Tools for Young Children in Learning Mathematics

Manipulative tools are crucial for young children in gaining understanding of mathematical concepts.  Japan Math block sets serve as a bridge between concrete objects they see in daily life and the abstract concepts used in the world of math.

Young children do not have abstract concepts.  Adults can understand three apples, three cats, three liters of water, and a period of three days based on the concept of “3”, but children cannot.  They must first replace three apples, three cats, three liters of water, and a period of three days with three blocks, and then learn the rule that they are all “3”.  Such tools for replacing should be objects rather than pictures especially in the earliest stage of learning. Children acquire the concepts of numbers by using their own hands, and actually experiencing the increase and or decrease of objects.

We believe that manipulative tool is indispensable for our lesson books.  Japan Math Block Set has distinctive items and the design of each item maximizes the effect of our teaching materials.

### Items Included in Japan Math Block Set

Item Features
(1) Math Blocks (10 in clear case) Students compare numbers and compose and decompose numbers while naturally building their awareness of a “set of 10”.
(2) Math Blocks (10 in opaque case) Once students understand composition and decomposition using the clear case, they can practice making 10's using the opaque case.
(3) Math Block Picture Cards (10) For counting numbers from 10 to 100 as a substitute for math blocks.
(4) Counters (10 red and 10 blue) For counting objects and playing various number-related games.
(5) Red Dot Cards (10) Cards, with dots ranging from 1 to 10, work as a bridge to connect the number of concrete objects to numerical numbers.
(6) Number Cards (20) Cards, with numerals ranging from 1 to 20, teach how numbers correspond to numerals, which are abstract symbols of numbers.
