Home Connections Home Connection 26 H Activity NOTE TO FAMILIES This week we played an exciting game to practice mapping skills. In the game, both players are searching for buried treasure. Coordinate cards tell players where to go on the game board. At each space, players collect a certain number of buried gold pieces. At the end of the game, the player with the most gold pieces wins. Please have your child return the record sheet to school. You ll need a deck of coordinate cards, the game board on the back of this page, a record sheet, two game markers (a bean and a piece of cereal will do), and a pencil. Instructions for Buried Treasure 1 Set out your game board and place your deck of coordinate cards face down. 2 The first player draws a card, places his or her marker on that site, and writes on the record sheet how many gold pieces he or she found.

As players move to their new sites, they describe the paths they take. ( I started at C3 and went to A1. I went 2 spaces to the left and down 2 spaces. ) Keep a running total of your collection of gold pieces as you play.

Home Connection 28 H Activity NOTE TO FAMILIES We d like to show you how to make a special cup from folded paper. Follow the diagram, folding and talking about the shapes you see in the cup. When you have made a set of cups, fill them with cereal, popcorn, or a food of your choice. Enjoy! If you enjoyed this paper folding activity, you may want to check out a book on origami from the library. Please have your child complete the worksheet on the back of this page and return it to school. You ll need the directions below and one piece of square paper each. Instructions for Making a Paper Cup 1 2 3 fold 4 5 6 Reopen and fold corners to center to form a hexagon long edge short edge Fold in half to form a trapezoid. Fold in half to mark the dotted center line and then open up. Fold corners as indicated (along center fold). 7 8 9 Both corners are folded. Turn square over; open diagonal edge and fold triangles over bottom edge. Enjoy! The Math Learning Center Bridges in Mathematics 161

Home Connection 29 H Activity NOTE TO FAMILIES Students have enjoyed this game at school and would like to teach it to you this week. You ll each take turns spinning, sketching, and computing the product for larger multiplication problems. For each problem, you ll sketch an array to show the product (the total). Your child can show you how, and we ve included an example for your reference. Your child will need to complete and return the practice worksheet to school. You ll need a spinner, paperclip, pencil, and record sheet to play Spin & Multiply. Instructions for Spin & Multiply 1 Record both players names on a Spin & Multiply Record Sheet. 2 Spin each spinner to get two numbers to multiply. 3 Sketch the frame of linear pieces onto the grid on the record sheet first, and then fill in the array. Explain how you computed the product of those two factors to your family member. H ome Connection 29 Activity (cont.) Spin & Multiply Record Sheet S tudent Darrell 24 140 7 + 28 168 7 x 24 = 168 4 You and your partner will each take 3 turns spinning, sketching, and finding the product. 5 When you have both taken 3 turns, find the sum of your products. Your partner should do the same. Doublecheck each other s work. 6 Spin the More or Less Spinner to determine who wins the game. If the spinner lands on More, the player with the higher sum wins. If the spinner lands on Less, the player with the lower sum wins. First I saw the 70 plus 70. That s 140. I forgot 7 times 4 is 28, but I saw it was 14 plus 14. 140 plus 28 is 168, so that means 7 times 24 is 168. If you don t know the answer, you can draw the array and add all the parts together.
