This worksheet is designed to give students practice of adding ones to two digit numbers mentally and using formal methods whilst also providing concrete representatives of these additions.
Section A uses base 10 blocks as visual aids for addition problems. Students are asked to complete additions of single-digit numbers to two-digit numbers using these blocks.
Then in section B, students will mentally add a single digit to a two digit number as they complete three addition wheels, where the number at the centre is added to the number outside of it.
Section C introduces a formal method for addition as students complete a series of column additions.
No regrouping is required throughout.
