Big Idea: 3-digit numbers can contain a “hundred," which is equal to 10 groups of 10.
This lesson builds on previous lessons' work with two-digit numbers. The task asks students to model the three-digit number shown in the question according to guidelines, i.e. with only hundreds and tens. This approach gives students support in building three-digit numbers; the base ten blocks give students a jumping-off point for their thinking. For instance, they can immediately think about how they could show 21 in only ones instead of tens and ones.
Special Materials: Base Ten Blocks

According to Achieve the Core, (achievethecore.org), "The joint purpose of this task is to provide students an opportunity to practice two-digit subtraction with regrouping and to engage students in looking for and expressing regularity in repeated reasoning (MP.8). Throughout grade 2, students need many opportunities to practice subtraction in order to achieve fluency subtracting within 100 by the end of the grade. For students in grade 2, it is sufficient for them to recognize that differences of 9 will stem from numbers whose digits differ by 1, subtractions resulting in 18 will stem from numbers whose digits differ by 2, etc. "

The IceCube VR experience puts you in the role of an astrophysicist who journeys deep into space to track down the source of a neutrino detected by the IceCube observatory in Antarctica. At the research station at the South Pole, you will see the large instrument, buried in the ice, detect a mesage from across the universe. Using your “impossibility drive,” you will follow the neutrinos path back to the black hole it was emitted from. Along the way, you will be able to take in awe inspiring views from the edge of the solar system, looking back from the milky way and dangerously close to a black hole. You will be able to see using not only your normal visible spectrum, but also using X-ray vision and neutrino vision, revealing entirely different views of space.
