Which strategy best explains how to solve this problem? colin is preparing for a marathon by running in his neighborhood. the first week, he runs one block. the next week, he runs twice as many blocks as the first week (2 blocks). each week, he plans to run twice as many blocks as he ran the week before. how many blocks will colin run by the end of the sixth week? a. use objects to model the problem. put out 1 chip to represent the blocks run in week one. put out twice that amount for week two. put out twice that amount (from week two) for week three. do this 3 more times, putting out twice the amount from the previous week each time. b. make a table. in the first row, write first week - 2 blocks. in the next row, write second week - 4 blocks. in the third row, write third week -6 blocks. continue this pattern for three more rows. c. write a number sentence. (1 + 2) × 6 = x add the number of blocks run in the first and 2nd week. then multiply the sum by the number of weeks (6).

E) invented multi-digit addition strategies [4pts] show two invented (efficient) strategies that a student could use to solve 76+29. represent each strategy using both symbols and a model (e.g., base-10 blocks or an open number line). an 'invented strategy is not the standard us algorithm and is not a direct modeling or counting strategy if you were using base-10 blocks to solve the problem, you would be direct modeling, but here you're using the blocks to show how your invented strategy works, not to solve the problem, so it's okay to use those as your model. consider using color to show connections between the symbols and the model. 76+29 first strategy model symbols second strategy model symbols

There are four base-two block sizes. position place value block model 1 ones (units) 10 twos 100 fours 1000 eights (a) write the binary number represented by the base-two blocks. 1101 correct: your answer is correct. (b) what base-ten number is represented by the binary number in part (a)? (c) what is the largest binary number that can be modeled using the four sizes of base-two blocks? what base-ten number is represented by this binary number? (d) describe the set of base-ten numbers whose binary representations can be modeled with the four sizes of base-two blocks. the base-ten numbers that can be represented with the four sizes of base-two blocks are the numbers from (smaller value) through (larger value).
