Have you seen learners using their fingers adding one or two digit numbers? But, the skill or ability to add numbers mentally greatly improves achievement in mathematics, right? This 3-page worksheet offers practice in mastering addition without counting. (Includes answers.)

DESCRIPTION

• Practicing regularly with this table improves mastery of addition up to 20 (with zero) before moving on to subtraction.
• Answers are included to show with examples what to do, for learners to be confident that they are capable mathematicians.
• This table improves mental addition skills.There are three stages of progression in learning addition:
1. Counting strategies: Use objects or fingers to count verbally to determine the answer.
2. Reasoning strategies: Use known information to logically determine an unknown combination: for example the learner knows that 5 + 8 is 13, so 5 + 9 is one more, 14.
3. Mastery or efficient production of answers: Learners can determine the answers fast and accurately, without having to count with their fingers or objects and without having to reason to get the answer.
• Fluency and ease in adding whole numbers is useful to learn because it aids in all calculations: addition, subtraction, multiplication and division.
