Achievements
Achievements in accordance with the records of the core curriculum for primary school, grades I-III
Computer science education: the student solves tasks, puzzles, and riddles leading to the discovery of algorithms; uses a computer or other digital device and external devices to perform a task; associates the operation of a computer or other digital device with the effects of working with software; cooperates with students, exchanges ideas and experiences with them, using technology.
General Objectives
- improving spatial orientation,
- developing the ability to apply algorithms,
- shaping the ability to understand basic mathematical concepts and operations, along with describing these activities: in words, image, symbol.
Operational Objectives, Student
- orders the results of addition and subtraction from smallest to largest,
- arranges the route using blocks with directional arrows,
- determines the mutual position of objects on the plane,
- determines directions and establishes the position of objects in relation to oneself, as well as in relation to other objects, distinguishes the left and right side.
Description of work with the application
Launch the "Add and subtract until the finish" application. Tell the students that on the Planet of Scientists, Ava has many tasks to do, but it is difficult because many paths are encrypted. Ava needs to find the Counting Office. The road to it is encrypted with numbers that need to be added or subtracted from the subsequent results on the route. Choose the board size suitable for your students. Help Ava determine the route using blocks with arrows, taking into account the numbers that, when added or subtracted, will give the result given at the finish.
