Develop and master skills and concepts by solving problems that integrates content areas, using strategies and tools.

Multisolution strategies

EALR's:

1.1, 1.4, 1.5
2.1, 2.2, 2.3
3.1, 3.2
5.3

Patterning

EALR's:

1.1, 1.3, 1.4, 1.5
2.1, 2.2, 2.3
3.1, 3.2, 3.3
4.2, 4.3
5.1

Measurement

EALR's:

1.1, 1.2, 1.4, 1.5
3.1, 3.2
4.2, 4.3

Using the TIMS laboratory method, students investigate the height, arm span, hand span, and cubit of their peers. Students hypothesize about the generality of the data to other children of the same age as well as different ages.

EALR's:

1.1, 1.2, 1.4, 1.5
3.1, 3.2

Students transition from nonstandard to standard units for the measurement of length. They use centimeters and meters to measure and compare the distance different vehicles can roll in the lab, Rolling Along in Centimeters. They learn about the need for controlling variables in an experiment, and why scientists conduct the same experiment multiple times.

EALR's:

1.1, 1.2, 1.5
2.1, 2.3
3.1, 3.2

Students learn about place value in two- and three-digit numbers using connecting cubes, place value mats, and base ten pieces. They group, partition, trade, and order numbers. In the lab, Marshmallows and Containers, students explore the relationship between the shape and volume of a container.

EALR's:

1.1, 1.2
2.1, 2.3
3.1
4.1, 4.2

Students build three-dimensional models with connecting cubes. They study ways they can compare, contrast, and sort their cube models. Students develop “cube model plans” on paper as a simple way to represent their three-dimensional structures. They build models from plans they are given, and they make plans for models they have built. They find the volume of their cube models by counting the number of cubes in the model.

EALR's:

1.1, 1.3
2.2, 2.3
3.1
4.3
