Under Number of Triangles, write, Add 2 more toothpicks to create 2 triangles. 4. In the chart, under Number of Toothpicks, write, 5. Under Number of Triangles, write, Continue this process until you have added 10 triangles. 6. Without creating another triangle, can you tell how many toothpicks you would need for an eleventh triangle? A twelfth? Fill in the table and explain the pattern. What about the 25 th triangle? (Use your pattern to predict this)

5 Puzzle It Out What you need: 13 index cards Marker 1. Write the numbers 0 to 9 on separate index cards. 2. On the last three index cards, write +, -, and 3. Using each number only once, create a true equation using 2 and/or 3 digit addition or subtraction. Example: or Record these examples in the table. Addition or Subtraction Sum or Difference

6 Fishy Bowls What you will need: Blank white paper or white construction paper Scissors Colored pencils, markers, etc. 1. Draw and cut out a symmetrical fish bowl at least 8 inches wide and 8 inches high. Examples: 2. Draw 10 fish inside the fish bowl and color the fish by adding spots, stripes, and other traits. 3. Write five sentences about the combination of fish in the bowl using fractions. Simplify where possible! For example, if 3 of the fish have stripes: 10 3 of my fish have stripes. 4. Now, write five more sentences converting this to 100 fish in a fishbowl. 5. To finish, decorate your bowl!

7 Roll to a Meter What you will need: 2 dice Recording Sheet Pencil Partner to play against (optional) 1. Roll the dice. 2. Add the numbers on the dice Example: 7 3.

Write this value as a decimal under, Decimal notation of a meter total. 6. If you are playing with a partner, your partner takes his or her first turn and follows steps 1 5.

8 7. Roll the dice again. Under How many cm did you roll, add this value to your original value and continue to fill out the chart. 8. Continue this process until you reach exactly one meter. The first player to reach exactly one meter (or gets the closest) wins! Roll Number How many cm did you roll? Fraction of a meter total Decimal notation of a meter total

9 State Bird Challenge What you will need: Access to a library or computer Pencil 1. Research 10 state birds in different locations and report on their average wingspans in inches, colors, average weights, and food using the table below. 2. Plot the wingspans on a number line. 3. What state has the bird with the biggest wingspan? Can you make any connections with the region the bird is from and their wingspan? With any other features such as their colors, sizes, food they eat, etc? Bird State Wingspan (inches) Color(s) Weight (grams) Example American Robin CT 36 Brown and orange 81 g Food Insects, fruit, and berries

10 What you need: A ruler Pencil Construction paper Scissors Glue or Tape Make a Peacock 1. Create the body of the peacock by making an isosceles triangle with a base of 2 inches and a height of 6 inches. 2. Create feathers (these should all be different colors) by cutting out 6 right triangles: 2 with 2 inch bases and a height of 5 inches 2 with 1.5 inch bases and a height of 4 inches 2 with 1 inch bases and a height of 3 inches 3. Arrange the feathers symmetrically so there are 3 feathers on each side of the body. 4. Create the head by making a circle with a 2 inch diameter and two eyes that are circles. 5. Create the feet by making two small congruent right triangles. 6. Create the beak but cutting a rhombus, folding it in half along the obtuse angles to make 2 triangles, and gluing down 1 triangle so the mouth appears open. 7. Create the crest by cutting a triangle in which no side is more than 1.5 inches. Fringe the top side and glue to the top of the head.

11 Origami Jumping Frog What you need: One rectangular piece of paper (computer paper would work best) Markers, crayons, colored pencils, etc. for decorating 1. Fold the paper in half like a hot-dog. 2. Fold the top right corner to the opposite edge of the paper (making a right triangle) and crease the edge. Unfold. 3. Fold the top left corner to the opposite edge of the paper (making a right triangle and crease the edge. Unfold.

12 4. Where the diagonal creases meet, fold the paper to create a rectangle. Crease and unfold. 5. Take the bottom left and right corners of the rectangle and push to line up at the center fold. This should create a triangle. 6. Fold the bottom left and right corners to the top of the triangle to make a small square. 7. You should now be looking at a pentagon. Fold the sides of the pentagon into the center line so they line up.

13 8. You should now have a pentagon that has two very long sides. Fold the bottom of the pentagon up such that the bottom corners line up with the top corners of the sides. 9. You should now have a smaller rectangle. Fold this rectangle in half downward so the top two corners match up with the bottom two corners. 10. Turn it over and you now have your frog! To make him jump, press down on his back. Decorate your new frog! Examples: If you make frogs out of different size rectangles, do they jump further? What conclusions can you make?
