How do I find the tools, like to make mortar & boards. One is a pic of a gardening tool and one is..

Look on the order board, and there may be an order which gives you some tool items as a reward, this is indicated by a tool box image. If there are none there, complete some of the existing orders that you can, and hopefully one of the new orders will give the toolbox reward.

Otherwise you can check the daily rewards and sometimes you find them by clearing parts of the map in crates etc...
