Indicator “Arithmetic operations: Finding the components of addition and subtraction” allows you to determine the level of formation of a basic knowledge of determining the components of addition and subtraction, understanding the relationship between them as well as the ability to check addition and subtraction within 20 correctly.
According to the results of the test, it can be stated with a high degree of probability that the student, unfortunately, doesn’t understand a connection between the actions of addition and subtraction, and their components. Most likely, he/she does not check the final results of the calculations of the addition and subtraction operations. Moreover, there is no skill that allows him/her to focus on the number line when looking for the components of addition and subtraction, and to select the unknown components of actions in equalities. The student cannot independently establish a connection when searching for the components of addition and subtraction.
To develop this skill, we recommend regular exercises with materials:
