In today’s lesson, we reviewed addition and subtraction problems using various examples from past benchmark papers, including solving 142 + 241 to get 383 and identifying an unknown number as 757 when solving a subtraction problem. We also tackled a similar problem from the 2014 benchmark paper, calculating 136 + 864 to equal 1000 and found that subtracting 99 from 2002 results in 1903. Additionally, we practiced completing a number pyramid using subtraction, determining that the unknown value from 312 – 288 is 24.
