They understand the properties of and the relationships between plane geometric figures. They collect, represent and analyze data to answer questions. 1.9 identify the relative position of fractions, mixed numbers, and decimals to two decimal places on the number line 2. Students extend their use and understanding of whole numbers to addition and subtraction of simple decimals. 2.1 estimate and compute the sum or difference of whole numbers and positive decimals to two places 2.2 round two place decimals to one decimal or the nearest whole number, and use rounding to judge the reasonableness of an answer 3.
Students know how to factor small whole numbers.
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.
