Add And Subtract Within 20: Tips, Tricks and Strategies.

Add and Subtract Within 20 Game: Tips, Tricks, and Strategies

Following are Tips, Tricks and Strategies to help you excel in the "Add and Subtract Within 20" game:

Tips:

• Practice basic addition and subtraction facts within 20 to build a strong foundation.
• Break down larger numbers into smaller, more manageable parts to make calculations easier.
• Use visual aids like number lines, counters, or manipulatives to help visualize the addition and subtraction processes.
• Focus on accuracy rather than speed. Take your time to ensure correct answers.
• Work on mental math skills by practicing quick calculations without the aid of external tools.

Tricks:

• Use number bonds to break down numbers into their component parts. For example, to subtract 7 from 15, think of 15 as 10 + 5 and subtract 7 from each part separately.
• Learn and memorize common addition and subtraction patterns, such as doubles (e.g., 6 + 6 = 12) and near doubles (e.g., 6 + 7 = 13).
• Utilize known facts to derive unknown ones. For example, if you know that 7 + 3 = 10, you can easily calculate 7 + 4 by adding one more.
• Use the commutative property of addition to your advantage. For example, instead of calculating 8 + 5, you can think of it as 5 + 8, which may be easier to solve mentally.

Strategies:

• Estimate the answer before calculating to develop a sense of number and improve efficiency.
• Break down complex problems into simpler steps. Solve one part at a time and then combine the results.
• Look for patterns and relationships between numbers to make calculations more intuitive.
• Practice mental math regularly to improve your speed and accuracy.
• Challenge yourself with timed drills or online games to sharpen your skills.
