Here is my first idea. In a J environment JHS the students could explore the following ideas and extemd them in creative ways in an ways they could. The focus THis on counting, shapes, patterns, colors and addition tables. Example: This code works in jqt. It works expecially well in the beta J803. The last remaining problems are gone. If students had J they could make many different images and go in many directions with only this on start. Experimentation is one of the keys to encouraging learning. The code also can be used in jqt and the images appear separately. load 'viewmat' ]GRB=:1 0 2{"1 (#:i.8){0 255 GRB viewmat i.16 ]C=:i.12 GRB viewmat C ]D=:3 4$i.12 GRB viewmat D ]M=:5 3$i.15 GRB viewmat M GRB viewmat 7 3$i.21 ]B=:4 4$i.16 GRB viewmat B GRB viewmat |: B GRB viewmat |.|:B ]T=:+/~i.16 GRB viewmat T;'T' Grade 1 Overview Operations and Algebraic Thinking * Represent and solve problems involving addition and subtraction. * Understand and apply properties of operations and the relationship between addition and subtraction. * Add and subtract within 20. * Work with addition and subtraction equations. Number and Operations in Base Ten * Extend the counting sequence. * Understand place value. * Use place value understanding and properties of operations to add and subtract. Measurement and Data * Measure lengths indirectly and by iterating length units. * Tell and write time. * Represent and interpret data. Geometry * Reason with shapes and their attributes. Mathematical Practices 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. Please think about the first grades you know or remember and contribute and ideas you think might be useful. ---------------------------------------------------------------------- For information about J forums see <http://www.jsoftware.com/forums.htm> http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
