Concrete resources, also known as manipulatives, are physical objects that children can pick up and manipulate to improve their maths knowledge. Used in maths education, a variety of concrete maths resources can help children to understand the relationship between numbers and the number system.
What are the five keys to success in mathematics?
They were based on five key areas 1) Representation, 2) Reasoning and Proof, 3) Communication, 4) Problem Solving, and 5) Connections. If these look familiar, it is because they are the five process standards from the National Council of Teachers of Mathematics (NCTM, 2000).
How do you teach a child to Subitise?
Showing children ‘quick images’ and asking them how many they see is one way of developing subitising. An alternative way of developing conceptual subitising is to show children a number of dots and ask them to say how they see the number (see the NRICH activity Number Talks).

Subitising is a term that was introduced by the Swiss psychologist Piaget. It’s the ability to look at a small number of objects and instantly recognise how many objects there are without needing to count.
What is the difference between algebra and abstract algebra?
Whereas elementary algebra treats equational reasoning in a particular algebra such as the field of reals or the field of complex numbers, and abstract algebra studies particular classes of algebras such as groups, rings, or fields, universal algebra studies classes of classes of algebras.
Is math real or abstract?
One of the significant questions in the idea of mathematics is: “What is mathematics?” Mathematics is an abstract object for most of us.

Why is math an art?
Mathematics has itself been described as an art motivated by beauty. Mathematics can be discerned in arts such as music, dance, painting, architecture, sculpture, and textiles. The engraver Albrecht Dürer made many references to mathematics in his work Melencolia I. In modern times, the graphic artist M. C.

Recorders are typically held at an angle between vertical and horizontal, the attitude depending on the size and weight of the recorder, and personal preference. Pitches are produced on the recorder by covering the holes while blowing into the instrument.
