Students know the concept of angle measurement and use a protractor and compass in solving problems.
They use grids, tables, graphs, and charts to record and analyze data. Students compute with very large and very small numbers, positive and negative numbers, decimals and fractions and understand the relationship between decimals, fractions and percents. They understand the relative magnitudes of numbers. Students perform calculations and solve problems involving addition, subtraction and simple multiplication and division of fractions and decimals. Students use variables in simple expressions, compute the value of the expression for specific values of the variable, and plot and interpret the results.
