Rekenrek 101: Pushing Mathematical Understanding with Alexandra Ivy

What is a Rekenrek?

A Rekenrek is a simple yet powerful math manipulative that can be used to teach a wide range of mathematical concepts, from number sense to fractions. It consists of a wooden frame with 10 rows of 10 beads. The beads are arranged in a alternating pattern of red and white, with the red beads representing the digits 0-9 and the white beads representing the digits 10-19.

How to Use a Rekenrek

There are endless ways to use a Rekenrek to teach math. Here are a few basic ideas to get you started:

• Counting: Children can use the Rekenrek to count to 100. They can also use it to count by 2s, 5s, and 10s.
• Number sense: Children can use the Rekenrek to learn about the different ways to represent numbers. For example, they can see that the number 15 can be represented as 10 + 5, 5 + 10, or 15 + 0.
• Number relationships: Children can use the Rekenrek to explore the relationships between numbers. For example, they can see that 10 + 5 = 15, 15 - 5 = 10, and 15 ÷ 5 = 3.
• Addition and subtraction: Children can use the Rekenrek to solve addition and subtraction problems. For example, they can use the Rekenrek to solve the problem 10 + 5 = ?. They can also use the Rekenrek to solve the problem 15 - 5 = ?.
• Multiplication and division: Children can use the Rekenrek to solve multiplication and division problems. For example, they can use the Rekenrek to solve the problem 5 x 3 = ?. They can also use the Rekenrek to solve the problem 15 ÷ 3 = ?.
• Fractions: Children can use the Rekenrek to learn about fractions. For example, they can see that 1/2 of 10 is 5. They can also use the Rekenrek to solve fraction problems, such as the problem 1/2 + 1/4 = ?.

Benefits of Using a Rekenrek

There are many benefits to using a Rekenrek to teach math. Here are a few of the most important benefits:

• Rekenreks are concrete. This means that children can see and touch the beads, which helps them to understand the concepts they are learning.
• Rekenreks are manipulative. This means that children can move the beads around to explore different mathematical concepts.
• Rekenreks are engaging. Children love to play with Rekenreks, which makes learning math more fun and enjoyable.
• Rekenreks are affordable. Rekenreks are relatively inexpensive, which makes them a great option for schools and families on a budget.

Rekenreks are a valuable tool for teaching math. They can be used to teach a wide range of mathematical concepts, from number sense to fractions. Rekenreks are concrete, manipulative, engaging, and affordable. If you are looking for a way to make learning math more fun and effective, I encourage you to give Rekenreks a try.
