Vegetable Garden Project

Area is the number of square units that cover a 2-D surface.

You can determine the area of two-dimensional shape by counting the square units within it.

Your challenge is to design a vegetable garden.

1. A. Choose Your Vegetables

Subtraction Game from 50

1 dice, pencil and paper

2 or more players

Each player begins with 50 points. The last player to have points leftover is the winner.

Players take turns rolling the dice until they roll a 1. Each new amount rolled is mentally subtracted from the previous one. At the end of the turn, the player records the total difference on the paper. If a player rolls a 1, the turn ends and the next player takes a turn.

When a player has no points they are out of the game. This game could be played with 2 dice.

This game could be played from 100.

Creating Dice

Draw or use this shape. Cut the dice out along its outside border.

Fold the dice along each of the six sides (along the lines).

With small pieces of clear tape, tape each edge to another edge. You should get a nice cube.

Roll the dice to see if it works, then play the Subtraction game!!

Your dice may be a bit lopsided, but it should work. You may have to make several dice to get one you like.

Price comparison

Look through your weekly flyers or listen to the radio for the prices of vegetables at your local grocery stores. Compare the costs of fresh, canned and frozen vegetables. Considering the prices in your table which of the options (fresh, canned or frozen) is your preference?

Grade 5 - Numeracy

It’s Magic!

A magic hat returns 3 times as many things as you put in it. What if you put in 235 dimes in the hat. How many dimes would you get back? Challenge: How much money would this be? Make your own magic hat question! Note: A dime is worth ten cents.

Mystery Number

You read a whole number and say exactly 5 words. What might the number be?

Challenge: Can you think of a number when read aloud that uses 6, 7, 8 or 9 words?

Seed it!

The school field needs to be seeded. The measurements of the field length and width given below are in meters. How can you find the area of this field? Show your method. Challenge: If a bag of seed covers 100 square metres, how many bags of seed would you need to buy in order to seed the field?

NOTE: This model is represented in base ten blocks. Area is defined as the surface covering the field.

Variable Riddles

Solve for my variable:

I subtract 6 from n and have 13 left. What is n?

Four more than p is 37. What is p?

Two more than w is 23. What is w?

One less than k is 27. What is k?

Two times a number p is 14. What is p?

Half of r is 6. What is r?

NOTE: A variable is a symbol (letter) for an unknown number.

Stick Math

For each Stick Pattern shown: Find a quick way to count the number of sticks in a pattern without counting all the sticks. Record your answer. Gather the same number of sticks outside. Make the pattern as shown in the picture on the ground. Was your answer correct? What was your quick counting method? No Sticks No Problem: draw each pattern on paper.

Activity Two: Create some stick patterns of your own. Work out a quick-counting method and then ask someone to work out their own quick-counting method. Compare your methods.

Creative Math (60 min)

10-sided Dice Template: Cut out the paper template. Glue the template on cardboard (food box). Cut out the template. Fold along the inside lines. Put glue on each tab or join with transparent tape. We found that small pieces of tape worked better. Assemble and label the sides of the dice with the digits 0-9.

Rolling the Facts

Roll the dice twice. Multiply the numbers. Repeat to practice the multiplication facts.

Outdoor Math - Sticks and Stones

A game for 2 players.

Materials: stones, sticks, game board

Prep: Gameboard: Draw a square with 5 rows and 6 columns creating 30 spaces. You can draw the game board in the dirt/sand with a stick or use chalk on the pavement. Find some counters outdoors: 12 per player (example: player 1 has 12 sticks, player 2 has 12 stones or other objects such as shells, buttons, etc.). Make sure each player has a different type of counter. Inside variation: Draw the game board on paper.

Game Set Up: Players take turns placing a counter anywhere on the game board until all counters have been placed. Players can have no more than three counters in a row, during game set up or while playing the game. Players can not remove each other’s counters, until play begins. When all counters are set, the game begins.

Play Begins: Players take turns moving one of their counters into an adjacent empty square forwards, backwards or sideways. The counters cannot be moved diagonally. The aim is to make three counters sit in a row (but not a diagonal row). When a player manages to make three counters in a row, they can remove one of their opponent’s counters. A player can only remove one counter from their opponent in any turn. The counter that is removed can be anywhere on the board, including from a row of 3. The game is over when a player is unable to make three in a row with their counters. The other player wins.

Stick with it! This game takes a few practice rounds to get the hang of it.

Grade 6 - Numeracy

Topics in Grade 6 math include Division, Fractions, Ratio, and Percent. This requires students to have a strong understanding of number sense. The following activities give students the opportunity to review, practice, and build on what they already know about these topics.

Saltwire: This activity has a required visual - See image “Math Reminders final” please put in colour at the start of grade 6 Numeracy above the activities.

Mental Math

Use the digits from 0 to 9 that you have created. As many times as you want, fill in the blanks to create a correct number sentence.

___ ___ is 50% of ___ ___ and 75% of ___ ___.

Example: 1 5 is 50% of 3 0 and 75% of 2 0 .

Let’s go grocery shopping!

In a grocery store flyer, select items for purchase. If you were purchasing six of the same item, approximately how much would it cost.

● Explain your estimating strategy and solve. Example: A bag of chips for $3.17 so 3 bags of chips would be about $3.20 x 3 = $9.60. Actual cost is $3.17 x 3 = $ 9.51.

● Does it pay for the store to have a promotion 3 for $8 on the chips? Why?

● Now you: Use the flyer to make a realistic grocery list. You must buy at least five boxes of Kraft Dinner and seven cans of soup (or items of your choice).

● Challenge: Repeat the activity but this time, you have $100 to spend without going over

Summer Job

You earned $800 last summer. 50% will be spent on a new bike. You donated 10% to the IWK Telethon and gave 15% to family for expenses. The remaining will be used to purchase a cell phone.

● How much was spent on each item?

● What is the ratio of money spent on cell to bike? IWK to bike?

● Use a number line to help solve.

Pizza Party

At Greco, three friends ordered 4 pizzas. Pierre ate five-thirds of the pizza while Mia ate five-fourths. Larry said that Mia ate more pizza than Pierre. Is Larry correct? How much pizza was left after Larry ate one whole pizza? Show using pictures, numbers, and words.

Time

One day = 1440 minutes.

● Estimate the time in minutes that you spend (eating lunch, sleeping, watching tv, playing a sport, walking).

● What fraction of the day is each? What are the part-to-whole ratios of each?

● Challenge: Can you convert your minutes to hours and complete the ratios?

Why is this?

Yesterday, Lakin tried to draw a triangle that had two obtuse angles but couldn’t do it, can you? Can you draw one with two acute angles? two right angles? Are these possible? Why or why not?

Grid Shapes & Angles

● Draw horizontal, vertical, and diagonal lines across the grid paper.

● Color in each shape.

● Label the shapes and each angle of each shape by number or letter.

● Now classify your angles as obtuse, acute, or right. Are there any reflex angles? straight angles?

● What types of polygons did you make?
