These Fraction Addition and Subtraction Bones skills in a fun and rewarding way.
Fractions can be seen as daunting to children at first. The task of adding and subtracting fractions can be even more so. If children have enough opportunity to practice working with fractions, they will become more accurate and less apprehensive. Using Fraction Addition and Subtraction Bones are an excellent resource for offering this type of practice.
Like fractions are fractions with the same denominator. You can add and subtract like fractions easily – simply add or subtract the numerators and write the sum over the common denominator. Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator.
The easiest way to find the least common denominator is to write the multiples of both denominators until you find a number they have in common. For example, to add the fractions 1/3 and 2/5, begin with some multiples of 3 (3, 6, 9, 12, 15) and some multiples of 5 (5, 10, 15). You’ll find that 15 is the lowest number that both numbers divide evenly into. So,15 is the least common denominator of 1/3 and 2/5.
The next step is to rewrite those fractions as like fractions. To re-write fractions as like fractions using the least common denominator,
It is essential for Foundation Phase and Intermediate Phase children need to have a solid maths foundation. Learning the concepts of Fraction Addition and Subtraction is an essential progression on their maths. Like all maths concepts, this concept needs to be well practiced.
Often learning these aspects of fraction addition and subtraction repetitive and boring. The Fraction Addition and Subtraction Bones are novel way for children to practice these essential skills. There are 50 different Bones offered in this pack.
How to use the Bones:
Each Bone has a “slider” that can be moved to conceal part of the maths sentence. Children need to calculate which part of the maths sentence has been concealed.
For example: In Fraction Addition and Subtraction Bones a Bone may have the Maths Sentence 2/8 + 4/8 = 6/8 The slider can be moved to conceal any part of this maths sentence.
The Fraction Addition and Subtraction Bones are 214mm x 60mm in dimension.
The “Bones” series of products are new to Learning Tools and we are very excited to introduce them to the South African market.
The Bones are screen printed onto the high quality yellow plastic. Research shows that black printed onto yellow materials optimises visual clarity. The Bones are manufactured and designed in according to the highest quality European standards.
