Students use and interpret variables, mathematical symbols and properties to write and simplify expressions and sentences. Students know how to manipulate equations. Students understand perimeter and area. Use these formulas to find the areas of more complex figures by dividing them into parts with these basic shapes 2. Students use two-dimensional coordinate grids to represent points and graph lines and simple figures.
Students demonstrate understanding of plane and solid geometric objects.
They use this knowledge to show relationships and solve problems. 3.5 know the definitions of right angle, acute angle and obtuse angle. Students organize, represent and interpret numerical and categorical data, and clearly communicate their findings. Students make predictions for simple probability situations. Students make decisions about how to approach problems.
