Grade 4RMs have been hard at work exploring different mathematical concepts. The last few weeks, we've inquired into growing number patterns, what is the rule, how do you extend the pattern and what are some strategies for finding the 10th, 20th, and 50th term.
These coming for weeks, relating what awe are learning to our unit of inquiry, we will be exploring measurement concepts : area, perimeter, and converting standard units.
Below are a few websites that are refreshers on what we've reviewed and explored thus far.
Stay tuned for the 4RM plans on solving the Grade 4 class size problem!
Addition and Subtraction
Powerlines. Students are presented with a gameboard and several sequential numbers. They are asked to place the numbers in positions such that each line is equal to the total that is displayed on the bottom of the page.
Circle 21 and Circle 99. In order to complete the puzzle, each circle must add up to 21 (or 99), using all of the numbers. When a circle is completed correctly, it changes color.
Home Run Derby Math. Students choose an operation (addition, subtraction, or multiplication), estimate the answer to a math problem presented on a baseball scoreboard, and then click "hit". The closer the estimate, the farther the baseball player hits the ball. Note that using a comma in one's answer results in a strike.
Patterns, Functions, and Change
Mental Maths. Drag a number into the machine, see what happens to it, and use that information to guess the rule. Students guess the rule by entering the operation and the number (e.g. ÷ 3 would mean the machine divides every number that goes through it by 3). Students can experiment as long as they like before making a guess.
Function Machine. Students have to guess the rule the machine is using to change numbers as they pass through it. The machine collects data about the numbers that have gone into and out of the machine. They guess the rule by entering the operation and the number (e.g. x 10 would mean the machine multiples every number that goes through it by 10).
