Kids Math Learning Tool - Number Bonds

Kids Math Learning Tool - Number Bonds 儿童教具 - 数字分合 Product Overview 本款数字10以内的数学教具设计，用于5岁儿童学习10以内的数字组合，可以直观显示10以内的数字是由几和几组成。 This mathematical manipulative is specially engineered for 5-year-old children to learn number composition within 10, offering an intuitive visual display demonstrating how each number from 1 to 10 can be split into two constituent numerical parts. Operating Instructions 按照图示组装后，转动读数手柄到想要的数字，再转动数字拆解手柄，读取蓝色与绿色的数量组合。 Assemble the teaching manipulative following the attached assembly schematic. Rotate the numeral selection knob to the target digit, then turn the number decomposition knob to read the corresponding quantity combinations of blue and green component blocks. Usage Example 示例：转动读数手柄到数字9，再转动数字拆解手柄后看到9是由3个蓝色与6个绿色组成，或是5个蓝色与4个绿色组成...以此类推 Rotate the numeral selection knob to digit 9, then operate the decomposition knob to view varied breakdown configurations of the number 9: such as 3 blue blocks matched with 6 green blocks, or 5 blue blocks paired with 4 green blocks, and all other valid combinatorial permutations of the target number.
