E1.5 Describe the relative positions of several objects and the movements needed to get from one object to another.

Skill: Describing Relative Location


In the Primary Division, children constantly observe their environment and establish reference points in order to situate themselves in the space around them. Children first situate people or objects in relation to themselves and then situate themselves in relation to other people or objects.

Example

3 characters are placed in a line, Tanya, an unknown character that represents the reader, and Tasha. A fourth character named Martin is behind the reader. There is a label below the drawing: "Martin is behind me. I am between T

To describe the location of an object, the student looks around the object to find benchmarks.

Example

On a shelf, a teddy bear is placed on the highest shelf. Next to the teddy bear, there is a balloon and 3 books. On the middle shelf, there is a vase. A label below the drawing shows: "The teddy bear is placed on the shelf, next to the balloon, above the vase."

To locate an object, the child first selects or identifies an object as a benchmark. Then, they combine several benchmarks to identify or locate objects according to a tracking system. For example, the child can recognize that the red lines in the gym are the boundaries for the students of their class. In Grade 1, they can locate a student in the classroom in relation to other students.

Example

image A grid of 4 columns and 4 rows. In each box there is a smiley face and a first name. From the top going from left to right: Amanda, Gilles, Elias, Chanda, Joseph, Peter, Tarek, Vanessa, Marie-Ange, Vincent, Sarita, Alexandre, Patrick. Nel, Sahar, Martine. A label below the grid: "I am to the right of Marie-Ange, to the left of Sarita, in front of Peter and behind Nel."

Skill: Describing a Movement


Children arrive at school with prior experience in moving through their environment. Over the years, their vocabulary evolves and allows them to describe the movements with greater precision.

Translation

Prior to Grade 4, students perform translations without knowing that they are translations. For example, he or she puts things away, changes the position of various objects, and moves from one place to another. Teachers give directions so that the student can move to get an object, go to the washroom, or to the secretary's office.

In Grade 1, students describe movements in a grid using four directions: right, left, up, and down. Students can describe a movement, both in terms of distance and direction using words or symbols.

Example

A grid of 3 columns and 3 rows, a rabbit is in the first box, of the first column, and another, in the first box, of the last column.

In Grade 2, students learn to express movement more precisely. They make horizontal and vertical movements on a grid. They use a tracking system to describe direction (right, left, up, down) and distance (number of squares).

Example

A grid of 4 columns and 4 rows. An initial " shape " triangle is placed in the first cell of the second column. The "image" triangle is placed in the last square of the third column.
