Estimating by Rounding – Matching activity
Added by Elizabeth on August 1, 2015
A great resource for prompting discussion around estimating and rounding.
Students are faced with 9 matching pairs of calculations and the corresponding estimated answer. Numbers should be rounded to 1 significant figure before calculating.
This resource could be used as a ‘cut and stick’ activity, laminated for repeated use or printed out for students to write down the matching pairs using the codes on the cards.
It is ideal for small groups or pairs but can be completed individually too.
UK: Suitable for both Key Stage 3 and 4 students.
