  2. Second Grade Termsto Maintain • Comparison of Numbers • Greater than, Less than, Equal to • 1230 is more than > 1229 • 1002 is less than < 1003 • 201 = 201

  3. Second Grade Terms to Maintain Addition and Subtraction of Multi-digits Numbers • Correctly adds/subtracts 2 whole numbers up to 3 digits with regrouping • Example: 981 + 179 = 981 – 179=

  4. Second Grade Terms to Maintain • Fact Families –Addition/Subtraction • Fractions-halves and fourths ¼ ¼ ¼ ¼

  5. Second Grade Terms to Maintain • Estimate to determine if an answer to a math problem is reasonable. • Rounding to nearest 100 • Skip counting/even and odd numbers

  6. CRCT Third Grade Terms • Place Value – ones, tens, hundreds, thousands, ten thousands and tenths • Picture Graphs/Venn Diagram hundreds ones Ten thousands thousands tens 1 1, 5 3 4 11,534

  9. CRCT Third Grade TermsGeometry • Geometry Shapes/Plane Figures – triangles, squares, rectangles, trapezoid, quadrilateral, pentagon, hexagon • Irregular Polygons-according to number of edges –Vertices Size of angles- right angle, obtuse, acute • Types of triangles – equilateral, isosceles, and scalene

  10. Pentagon – a flat shape with five sides

  11. Vertex/vertices Vertex- the point at which the sides of an angle meet. ∟ vertex

  12. Hexagon – a shape with six straight sides 2 1 3 4 6 5

  13. CRCT Third Grade Terms MATH SYMBOLS < less than 120 < 399 > greater than 400 > 299 = equal to 121 = 121 - difference - means to subtract

  14. CRCT Third Grade Terms • Decimal point – period put before a decimal fraction. The periods in .5 and .30 are decimal points. • Numerator/denominator • ¼ ¾ numerator numerator denominator denominator
