This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials - 2 clear plastic cups for each pair of students - 4 bean seeds for each pair - soil - unifix cubes - a plant or math journal to record data ...

This short video and interactive assessment activity is designed to teach second graders about adding unit lengths in one step (english units).

This lesson will allow students to build their own balloon car racer as an introduction to engineering and coding.  Each pair or team of students will be able to engineer their balloon car, measure the performance of their cars using yard sticks, and set up a basic algorithm to construct and run their machine.PURPOSEThe goals for this lesson are to: (1) integrate engineering and coding to young students; (2) have students independenty identify the steps (an algorithm) to build and improve their racers; (4) be able to spot "bugs" in their algorithm; (3) integrate measurement and addition operations to determine which car went furthest overall; and (4) teach perserverance by showing students that it is normal to find bugs in algorithms/coding.   

This Nrich problem brings in doubling, halves and quarters in a very practical way using rods made from interlocking cubes. It gives children a practical context in which to explore simple multiplying and dividing, even if these particular terms are not used explicitly. It can provide a very useful context for introducing and using the vocabulary of halves and quarters.

Don’t be S-s-scared: The Truth About Snakes was a six-month long learning expedition, during which second grade students became scientists, musicians, authors, and artists. They experienced the joys of the natural world and the pride of creating high-quality work about a topic that mattered deeply to them. From the start of the expedition, students aspired to be young herpetologists, scientists who study snakes and other reptiles.The expedition was written by teacher Jenna Gampel and published by EL Education.
