In maths we have been adding and subtracting to and from a 3 digit number. We created a human place value chart to see what happens to each column when we do this.

Can you work out the following sums? 324 + 9, 274 – 8, 432 + 9, 173 – 7, 436 + 70 , 527 – 30.

324+9=333

274-8=266

432+9=441

173-7=166

436+70=506

527-30=497

324+9=333

274-8=782

432+9=441

173-9=164

436+70=506

527-30=497

324 +9 = 333

274 – 8 = 266

432 + 9 = 441

173 – 7 = 166

436 + 70 = 506

527 – 30 = 497
