Black on white isn't great
The contrast of these colours is not helpful for dyslexic learners. Printing worksheets and other activities that require reading onto pastel shades is beneficial and you will notice all my PowerPoints have a pale blue background and the Smartboard activities are pale yellow. Ask your dyslexic pupils if there is a specific colour they prefer - my PowerPoints and Smartboard activities can be changed if it helps the pupils.
Cut down what they can see
Sometimes a whole page of text can be overwhelming but you don't need to create separate worksheets for your dyslexic pupils. Using two L-shaped pieces of card can block out any additional text that might be causing problems. These can then be moved around the text as needed. I tend to use the covers of old exercise books and keep a box of them at the back of my classroom for pupils to take as they need.
Use a dyslexia-friendly font
Dyslexia-friendly fonts tend to be large and sans serif. I chose to use SF Cartoonist Hand. This is a free font downloaded from the internet. After chatting with my sister about it, she said she still found it a little confusing. Increasing the spacing between the letters to "loose" solved the problem.
By providing pupils with sentence builders the individual words are created for them but they are still creating their own piece of writing. Giving them options of different verb endings and adjectival endings means they are having to work with their linguistic knowledge to create grammatically correct sentences just as they would have to do if they were writing pen to paper. All of my units of work come with sentence builders for this purpose.
