Learning to count, discovering numbers: the decimal number domino can provide a visual aid to this learning process. This article explains the pedagogical principles behind this tool and suggests a few activities. Warning The teaching guidelines given here are general. Whether you use them with dominoes or not, you can apply them to all other […]
How to use decimal dominoes to learn tens and counting to 100. That’s it, the pupils are counting to 10. They are used to adding and removing tokens one by one. They can count up from a pile of 5 and even create numbers by removing a few tokens, such as obtaining a 9 from […]
The examples presented in this article are for three-domino bars, which use numbers greater than 100, which allows us to understand carryover passages. Of course, we can use fewer dominoes to work on addition. If S is the sum of terms a and b : S <= 10: two unit domino bars are enough (there […]
As with addition, the examples presented in this article involve numbers greater than 100. It is of course possible to use dominoes with numbers less than 100. Subtraction Subtraction is not commutative: a – b ≠ b – a. The operand a is the one from which we will subtract the value b . If […]
