Decimals (through hundredths)
- Model multiplication and division of decimals by whole numbers
- Multiply and divide 1-digit and 2-digit decimals by whole numbers
- Compute using commutative, associative, distributive property
- Mental math and estimation/determine reasonableness
Algebra
- Represent unknowns using symbols such as □ and ∆
- Write and evaluate mathematical expressions using symbols
- Understand and apply patterns and rules to describe relationships and solve problems
Data
- Represent data (bar graph, pictograph, line graph)
- Compare a given set of data using different types of graphs
- Identify missing information and duplication in data
Geometry: 3-D figures and the Coordinate System
- Compare and contrast cubes and rectangular prisms
- Understand faces, edges, vertices
- Describe parallel and perpendicular lines in connection with rectangular prisms
- Construct/collect models of solid geometric figures to include cubes, cylinders, and prisms
- Understand and apply ordered pairs in the first quadrant
- Locate a point in the first quadrant and name the ordered pair
- Graph ordered pairs in the first quadrant
Here are some suggestions as to what you can do at home to help your child:
Multiplication and division of decimals by whole numbers can be practiced using money story problems:
If Jim works 8 hours at $5.56 per hour, how much will he earn?
Lee was paid $240 for 5 days of work. He worked 8 hours each day. How much does he earn per hour?
To practice problem solving skills, use a map with a distance key to plan a simple route to an interesting location or vacation site. Estimate the distance to the destination using the map. Estimate how long it will take to travel each way at an average speed of 50 miles per hour. Plan a travel budget including the cost of a motel, meals, admissions and souvenirs.
Help your child investigate mean, mode, median, and range using quiz grades.
Jules has taken 5 quizzes in math. Her scores are 98%, 89%, 79%, 86%, and 90%. Find the median (the number in the middle if you list the scores least to greatest) and range (the distance between the lowest and the highest score) of her quizzes. What is the mean (average) score?
Do the same with Tim’s scores: 89%, 83%, 59%, 79% and 82%. And Amy’s scores: 78% 99%, 89%, 79% and 93%.
What is the mode (the number that occurs most often) of these test scores?
Plan a party together for a family of 4. Using the following information estimate and then calculate the cost of the party supplies. Then calculate the cost per guest.
|
Paper plates |
12 for $1.98 |
|
Paper cups |
8 for $1.50 |
|
Lg. Pizza serves 8 |
$ 7.99 |
|
2 liters of soda serves 6 |
$ .99 |
|
½ gallon of ice cream – serves 4 |
$ 3.50 |
Now, plan a party for a class of 20 using the same information.
To help your child continue understanding of the coordinate system, play the following game together.
Grid Search
Materials: Grid paper
2 red pens and 2 blue or black pens
Each player draws two grids, label the vertical axis and the horizontal axis on both grids (see example).
Step 1 Players sit so that neither player can see what the other player is doing.
Each player secretly marks one point in red on grid 1. These are the “hidden”
points.
Step 2 Player 1 guesses the location of Player 2’s hidden point by naming an
ordered pair. For example, to name (1,3), a player would say, “1 comma 3”.
Step 3 If Player 2’s hidden point is at that location, Player 2 wins.
If the hidden point is not at that location, Player 2 marks the guess in blue or black on his or her Grid 1. Player 2 counts the least number of “square sides” needed to travel from the hidden point to the guessed point and tells the number to Player 1.
Step 4 Repeat steps with Player 2 guessing and Player 1
answering.
Step 5 The first player to identify the other player’s hidden
point wins.
