7 free worksheets with number charts dealing with the numbers up to 20 for 1st grade math.
Calculation tables or number tables are made up of columns and rows. Numbers are entered in the first column or in the first row. In the first space comes the number symbol. In our case the number symbol will only be plus or minus. Later, more complex mathematical symbols can be used.
You can use a variety of lessons through these tables and charts. The result, or answer, will always be at the sum of the two numbers. Students need diversity in the lesson, so that the repetition of the material does not become too boring. This is a great way to utilize the already learned material. You can also create these number tables yourself. Just remember not to go beyond the numbers we have learned so far. In our case, the numbers up to 20.
