Sometimes choosing a theme for a unit can help students get into their learning. I suggest trying a Minecraft theme. Even if you do not have Minecraft or MinecraftEDU for your classroom you can still create Minecraft themed activities. You could theme a math unit around the Minecraft blocks or ask students to do fictional writing using a character in a Minecraft world. Searching Minecraft party ideas will give you many resources you can repurpose for your classroom. Buzzfeed provides a list of resources to help create a Minecraft birthday party, try using some of these ideas to decorate your classroom with Creepers. Ambrosia Girl has a high resolution Creeper image you can download and use.
