This paper examines the implementation of unplugged tasks across different school settings developing computational thinking skills and concepts at upper primary school children in Spain without programming and without using electronic devices. The study is based on qualitative case study design. Across the three case studies/schools --…

Basic strategies for developing computational estimation skills are: (1) the front-end strategy, focusing on the front-end digits of the numbers; (2) the rounding strategy, rounding the original numbers to more manageable numbers; (3) the compatible number strategy, changing the original numbers to ones more similar and more manageable; and (4)…

Activities for reinforcement of whole number operations are provided through games that present strategic situations for children to use their computation skills. (JP)

Students who can compute mathematical problems in their heads have learned a skill that is important for estimating and for understanding the number system. Practice activities that can help students master mental computation skills are described. (PP)

Activities to develop counting skills are given. (MK)

This is an effective drill and practice activity that does not use consumable materials. It does not teach math facts, algorithms or concepts. It provides immediate feedback to the learner and can be easily modified for use in many curriculum areas. It is self correcting because the student can identify errors without assistance and provides…

Offers seven criteria for developing mathematical thinking, plus suggestions for teaching and assessing students' progress that are compatible with each learning criterion. Provides evaluation sheets that help the teacher assess and grade students on the criteria. (10 references) (MDH)

During the 1989-90 school year, the Barrett Math Program was piloted in selected sections of grades K-7 in five Atlanta (Georgia) Public Schools (APS) elementary schools. The Barrett Math Program is designed to improve the total mathematical skills of elementary school students, including computation, concepts, and problem solving, as measured by…

Detection of calculation errors, operation errors, and unanswerable problems was studied for 78 third graders and 77 fifth graders. The relationship between mathematics achievement and error detection was also examined. Older children and high achievers detected more errors than did younger students and low achievers. (SLD)

Developed to serve as a way to integrate mathematics skills and science processes, this booklet provides activities which demonstrate the concept of density for students of grades five through nine. Investigations are offered on the densities of water, salt, salt water, and woods. Opportunities are also provided in computing volumes of cylinders…
