In this lesson, students will use place value understanding to round multi-digit numbers to any place value using real world applications.
In this lesson, students learn how to round multi-digit numbers to the thousands place using the vertical number line.
In this lesson, students learn how to round multi-digit numbers to any place using the vertical number line.
In this lesson, students use multiplication, addition, or subtraction to solve multi-step word problems.
In this lesson, students will represent and solve division problems requiring decomposing a remainder in the tens.
In this lesson, students explain remainders by using place value understanding and models.
In this lesson, students will divide multiples of 10, 100, and 1,000 by single-digit numbers.
In this lesson, students interpret division word problems as either "number of groups unknown" or "group size unknown."
In this lesson, students interpret and find whole number quotients and remainders to solve one-step division word problems with larger divisors of 6, 7, 8, and 9.
In this lesson, students learn to solve multi-step measurement word problems.
This short video and interactive assessment activity is designed to teach fourth graders about using multiplication replacement to find a new amount.
Students explore materials engineering by modifying the material properties of water. Specifically, they use salt to lower the freezing point of water and test it by making ice cream. Using either a simple thermometer or a mechatronic temperature sensor, students learn about the lower temperature limit at which liquid water can exist such that even if placed in contact with a material much colder than 0 degrees Celsius, liquid water does not get colder than 0 °C. This provides students with an example of how materials can be modified (engineered) to change their equilibrium properties. They observe that when mixed with salt, liquid water's lower temperature limit can be dropped. Using salt-ice mixtures to cool the ice cream mixes to temperatures lower than 0 °C works better than ice alone.
Students investigate how mountains are formed. Concepts include the composition and structure of the Earth's tectonic plates and tectonic plate boundaries, with an emphasis on plate convergence as it relates to mountain formation. Students learn that geotechnical engineers design technologies to measure movement of tectonic plates and mountain formation, as well as design to alter the mountain environment to create safe and dependable roadways and tunnels.
Students recall multiplication to 10 x 10 and the corresponding division facts.
Students explore the concept of "reducing" solid waste and how it relates to product packaging and engineering advancements in packaging materials. They read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. Then they evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. In addition, students explore "hydropulping" and consider its use as a recycling process.
In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.
