Essential Questions for this unit are:
- What strategies can I use to multiply and divide decimals by whole numbers?
- How do quadrilateral relate to cubes and rectangular prisms?
- What is the relationship between a net and a solid figure?
- What properties of a solid figure can be determined by examining its net?
- How can graphing patterns be used to predict what will happen next?
- What are the advantages of working with a line plot when determining range, median and mode?
When we complete this unit, students should have an enduring understanding of the following topics:
- The same rules of computation for multiplying and dividing whole numbers are followed when multiplying and dividing decimals
- Multiplication of a decimal and a whole number is commutative in the same way as the multiplication of whole numbers
- A decimal fraction multiplied by a whole number has the opposite meaning of a decimal fraction divided by a whole number (4.5 x 5 = 5 groups of 4.5 which is opposite to 4.5 ÷ 5 = how many groups of 5 are found in 4.5?)
- There are many different ways to see and describe similarities and differences among shapes. The more ways that shapes can be sorted, identified and described the more they can be understood.
- Figures have properties that can be described and these can be used to analyze them. Properties can be explored and analyzed in a variety of ways
- A net is a closed plane figure that can be folded into a closed 3-dimensional figure. Nets help us to visualize the surface area of solids
- Data can be organized in various graphical form to visually convey information. Range, median and mode can easily be interpreted using the line plot
