Grade(s): 2-4 Objectives (grade dependent): Student(s) will be able to: use place value to compare and order whole numbers recall and apply addition and subtraction facts use patterns in numbers, relationships and operations identify and describe patterns to make predictions and solve problems identify models that approximate standard units of length use multiplication and division to solve problems round whole numbers collect, organize, record, display, and interpret data in bar graphs use organizational structures to analyze and describe patterns and relationships estimate and use tools to determine length make generalizations about determining all possible combinations identify the mathematics in everyday situations Supplies Needed (for each student): Copy of student page Pencil Measuring tool: size of footstep (heel to toe) or length of foot with shoe on TEKS (Texas Essential Knowledge and Skills) Alignments: Grade 2 111.14.b.1.A; 111.14.b.1.C; 111.14.b.3.A; 111.14.b.3.C; 111.14.b.5; 111.14.b.6.C; 111.14.b.9.A; 111.14.b.11.A Grade 3 111.15.b.3.A; 111.15.b.3.B; 111.15.b.4.C; 111.15.b.5.A; 111.13.b.13.A; 111.13.b.13.b Grade 4 111.16.b.3.A; 111.16.b.7; 111.16.b.11.A; 111.16.b.13.A; 111.16.b.14.D Background Information for the Teacher: Reptiles are one of the five classes of animals: amphibians, birds, fish, mammals and reptiles. They have several distinguishing characteristics that set them apart from other animals. As with all animals, there are exceptions to the rule, but for general purposes, all reptiles are cold-blooded, covered in dry, scaly skin, lay leathery eggs, breathe through lungs, have teeth, and have 4 appendages (arms and/or legs) with claws. There are 4 orders of reptiles: snakes and lizards, turtles, tortoises and terrapins, crocodilians, and the tuatara. All of these amazing animals are specially adapted for survival in their specific habitat. Many reptiles use patterns on their bodies to camouflage themselves for protection. Crocodilians have their nostrils and eyes situated high on the top of their head so they can stay hidden as they are
moving about in the murky rivers and swamps. Turtles have brown or dark green top shells the carapace to hide them within the forest floor and leaves. Some lizards even have the ability to change their colors to blend in with the different environments they inhabit. Many snakes can be identified through their scale patterns. Milk snakes are very common snakes in the world. Many people even have them as pets, as they are very docile and easy to take care of. Their pattern is: red, black, yellow, black. The coral snake looks very similar to the milk snake. Their pattern is: red, yellow, black, yellow. Of course, there are a few exceptions to the rules, so always use caution when around snakes in the wild. A common saying to distinguish the difference between the two snake species is: Red next to yellow, kill a fellow. Red next to black, friend to Jack.
Name SLITHER DOWN THE SNAKE WALK STUDENT PAGE 2ND GRADE 1. Walk down the snake pattern on the ground. How many of each color did you count? Black: Yellow: Red: Which color has the most? Which color has the least? Make a bar graph showing the number of bands of each color.
2. Look at your bar graph. Find the total number of bands. Is the total number of bands odd or even? Round the total number of bands to the nearest tens. 3. Look at the pattern on the snake. Write down the color pattern. Create another color pattern. 4. Pick a color band. Estimate how many of your footsteps (heel to toe) are in the band. Check to see how close you were.
Name SLITHER DOWN THE SNAKE WALK STUDENT PAGE 3RD GRADE 1. Count the red bands, the yellow bands, and the black bands. red yellow black Make a bar graph. Which color has the most? Which color has the least?
2. Use your bar graph. What is 1/2 of the yellow bands? What is 1/4 of the yellow bands? 3. Use your bar graph. Find the total number of bands. Is the total number even or odd? Round the number to the nearest tens.
Name SLITHER DOWN THE SNAKE WALK STUDENT PAGE 4TH GRADE 1. Count the red bands, the yellow bands, and the black bands. red yellow black Make a bar graph. Arrange the colors from greatest to least. > >
2. Starting from the head, look for the repeating pattern. Write down the color pattern. Are the colors in the same order as the order of the colors in Question #1? 3. The King cobras in the Zoo are about 10 feet long. Is the Snake Walk longer or shorter than the length of the King cobras? How many times longer or shorter? (Hint: use a measuring tool.)
