Looking for math words that start with E? This guide introduces useful E math vocabulary for elementary and middle school students, including equal, equation, even number, estimate, edge, exponent, equivalent fractions, and evaluate.<\/p>\n\n\n\n

These words connect to Common Core math topics such as operations, fractions, geometry, measurement, expressions, equations, and probability. Each E math word includes a simple definition, a kid-friendly example, and a quick activity so students can understand the term and use it in real math problems.<\/p>\n\n\n\n

Equal Sign<\/td>The equal sign shows that two sides have the same value.<\/td>In 6 + 2 = 8, the = sign means both sides match.<\/td>Write three number sentences with an equal sign and check if they are true.<\/td><\/tr>
Equal Groups<\/td>Equal groups have the same number of items in each group.<\/td>12 cookies can make 3 equal groups of 4.<\/td>Use counters to make equal groups, then write a multiplication fact.<\/td><\/tr>
Equation<\/td>An equation is a math sentence that shows two expressions are equal.<\/td>x + 3 = 10 is an equation.<\/td>Solve e + 4 = 9 using drawings or counters.<\/td><\/tr>
Even Number<\/td>An even number can be split into two equal groups.<\/td>8 is even because it can be split into 4 and 4.<\/td>Count objects and pair them up. If every object has a partner, the number is even.<\/td><\/tr>
Estimate<\/td>To estimate means to make a close guess, not an exact answer.<\/td>$4.95 is about $5.<\/td>Estimate the total price of two snacks, then add to check.<\/td><\/tr>
Exact Value<\/td>An exact value is the precise answer.<\/td>The exact value of 7 + 6 is 13.<\/td>Solve five addition problems, then compare exact answers with estimates.<\/td><\/tr>
Equivalent Fractions<\/td>Equivalent fractions have the same value, even if they look different.<\/td>1\/2 and 2\/4 are equivalent.<\/td>Draw two same-size rectangles. Shade 1\/2 on one and 2\/4 on the other.<\/td><\/tr>
Edge<\/td>An edge is where two faces of a 3D shape meet.<\/td>A cube has 12 edges.<\/td>Find a box and count its faces, edges, and vertices.<\/td><\/tr>
Endpoint<\/td>An endpoint is the point at the end of a line segment or ray.<\/td>A line segment has two endpoints.<\/td>Draw three line segments and mark each endpoint with a dot.<\/td><\/tr>
Expression<\/td>An expression is a math phrase with numbers, symbols, or variables, but no equal sign.<\/td>5 + 3 and 2x + 1 are expressions.<\/td>Write three expressions using addition, subtraction, or multiplication.<\/td><\/tr>
Evaluate<\/td>To evaluate means to find the value of an expression.<\/td>Evaluate 6 + 4 x 2 to get 14.<\/td>Pick three expressions and solve them step by step.<\/td><\/tr>
Exponent<\/td>An exponent tells how many times to multiply a number by itself.<\/td>2^3 means 2 x 2 x 2 = 8.<\/td>Build exponent towers with cubes: show 2^2, 2^3, and 3^2.<\/td><\/tr>
Equilateral Triangle<\/td>An equilateral triangle has 3 equal sides and 3 equal angles.<\/td>A triangle with all sides 5 cm is equilateral.<\/td>Draw a triangle and measure all three sides to see if they are equal.<\/td><\/tr>
Event<\/td>In probability, an event is something that can happen.<\/td>Rolling a 6 on a number cube is an event.<\/td>Roll a die 20 times and record how often each event happens.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n
