Multiplication and Division

Multiplication is the process of finding the total quantity when something is combined with itself several times. For example, if you multiply 5 by 6, it means combining 5 six times. It can also represent finding the area of shapes where length is multiplied by width. In contrast, division involves splitting things into equal groups or parts. When dividing by a number, this represents how many groups of the dividend can fit within the divisor without any leftovers. If there's a remainder, we usually call it a quotient followed by a fraction showing what remains.

Geometry

Geometry is one of the oldest branches of mathematics and deals with points, lines, surfaces, and solids. Basic principles include angles, symmetry, similarity, congruence, and congruent transformations. It focuses on measuring properties of space, such as distances between points, areas of surfaces, and volumes of solid figures. Points can be connected to form lines, which can intersect at angles; these angles are measured in degrees. Triangles, rectangles, circles, and other polygons are examples of geometric shapes.

Addition and Subtraction

Addition combines quantities together, while subtraction removes quantities from a larger set. These operations work best with small numbers initially, but they extend naturally to all real numbers, whether positive, negative, rational, or irrational. They involve processes like regrouping, carrying over, borrowing, and using both mental techniques and written methods.

Tessellation

Tessellation refers to the covering of a plane with regular shapes. A shape is considered to tessellate the plane if it repeats edge-to-edge with itself, without gaps or overlaps. Examples of regular tessellations include square grids, honeycomb patterns, and triangular lattice structures.

Word Problems

Word problems ask students to solve math problems based on information given in sentences rather than equations. These problems often require employing multiple mathematical skills, including arithmetic reasoning, algebraic manipulation, and problem solving strategies. Effective approaches for solving them typically involve careful reading, identifying key concepts, setting up an equation, solving it, checking your solution, and making sure it makes sense in context.
